PhysioSuite

The unit itself has a small footprint which allows for both the surgeon and monitoring technician to see the graph and digital readout, and does not require a computer for use.

phisio Suite -mouse-dr4-stem-cell-differentiation-neural-stem-cells-rat-models-gene-targeting

 

PhysioSuite Monitor

The PhysioSuite Monitor for mice and rats is a modular system that allows you to select the modules you need now, with the option to add more modules later. You can include up to four modules in one unit. The PhysioSuite significantly decreases the amount of space in the surgical area. The capacity of adding modules such as pulse oximetry & heart rate monitoring, artificial ventilation, ETCO2, temperature monitoring and homeothermic warming make the PhysioSuite even more space efficient. The built-in screen provides you with critical information that is easily visible and customizable. The real-time display screen has the capability to show numeric readings, waveforms, or both simultaneously. View historical data with the touch of a button.

 

MouseSTAT Pulse Oximeter and Heart Rate Monitor module

The MouseSTAT module does not need a computer to function. Though it was specifically designed for use on mice, with the proper sensor, it can be used on any size animal. Since the paws of small rodents are typically nude, no shaving or hair removal is required. Ideal for dark-skinned mice, such as C57BL6. Though some users apply the sensors to the tail, it is not recommended.

Pulse Oximeter Sensors:

The MouseSTAT Paw Sensor for mice (MSTAT Sensor-MSE) was specifically designed for small laboratory animals. It uses a miniature LED and light sensor to transmit and receive the red and infrared light that are proportional to the size and translucence of the small laboratory paw. One is included with every MouseSTAT module.

The larger MouseSTAT Y-style sensor (MSTAT Sensor-RAT) is ideal for penetrating thicker tissue, such as that on a rat or larger animal. It can be used on any animal and on any appendage with sufficient vascularization and irrigation. This can be a mouse paw, but more commonly is a rat paw, rabbit ear or small animal tongue.

cells-rat-knock-out-stem-cell-characterization-teratoma-formation

Mouse and Rat Paw Sensors

Other small laboratory animal pulse oximeters use human-size sensors mechanically adapted for small animals. These adapted human-sized sensors have large LEDs and light sensors that were designed to work on a human index finger or other like appendages. The large LEDs flood a boney appendage such as a finger with a tremendous amount of light, which is mostly absorbed or blocked by the bones and connective tissue. Since only a small amount of light passes through a finger, a large sensor is required to attempt to collect as much of the minute amount of transmitted light as possible.

When the human-sized sensors are attempted to be used on a translucent small laboratory animal paw, there is too much light delivered, which overflows the large light sensor. Therefore, the adapted human pulse oximeter sensors from other manufacturers need to use thick sections of the small laboratory animal body that approximate a human finger, such as the neck or thigh. Placing the sensor in these locations typically requires the extra effort of shaving the area. The higher force spring in the sensor clips may cause ischemia in the sensing area from the continuous squeezing pressure.

Other pulse oximetry systems also require a dedicated external PC to operate, which take up valuable lab bench and surgical area space.

All of the above can be combined into one PhysioSuite system – 1 box – eliminating the need for multiple boxes and systems.

RightTemp Temperature Monitoring and Homeothermic Control module

The RightTemp Temperature Monitoring and Homeothermic Control module is a complete kit that allows you to accurately monitor and maintain animal core body temperature. Simply set your desired core body temperature and the system will automatically control the warming pad so the animal's core temperature never goes above or below your set temperature.

Included with the RightTemp are two warming pads and two temperature sensors. The pads are 14" x 14" and 6" x 8", both ideal for mice, rats, and other small animals.

Multi-functional controller gives you 3 options for use:

  1. Control/maintain core body temperature by using both sensors

  2. Set desired pad temperature using the pad sensor only

  3. Adjust pad temperature by changing the percentage of power to the pad using no sensors

Features of the RightTemp Animal Warming module:

- Warm with or without sensors

- Configure up to 5 alarms

- Customize display

- Chart and view temperature readings for both pad and animal

- See the last 5 readings on the main screen

- Upload data to your computer

- Output data for use with strip chart software

About Far Infrared (FIR) Warming

The pads warm the animal through far infrared (FIR) warming. Far infrared light is absorbed by cells deep within the body of the animal which safely raise the core body temperature. FIR light warms the body without warming the air between the FIR source and the body. FIR is totally safe; in fact, 80% of the sun’s rays are in the low energy, far infrared range. FIR waves resonate with organic matter and penetrate deep into the body. The energy level of water in the body’s cells is gently increased through “resonant absorption” warming the inside of the body. The body can absorb as much as 90% of FIR heat compared to only 20% with conventional warming pads. Studies have shown that FIR can maintain therapeutic temperatures longer when compared with conventional heating methods. Less warming is required with FIR than with conventional techniques. FIR allows researchers to safely warm animals for a longer period of time without unknowingly overheating the animal. Your animal can now be warmed over an extended period of time without having to constantly increase the temperature.

FIR warming increases body metabolism, thereby discharging anesthetics and toxins, which aid in faster recovery from surgery.

Caspase-3 Assay for Apoptosis Detection in Whole, Living Cells 
Catalog no. 9125 (25-50 tests)

flica-660-caspase-3-assay-apoptosis-positive-jurkat-cellsApoptosis is an evolutionarily conserved form of cell suicide mediated by a cascade of proteolytic enzymes called caspases. Pro-apoptotic signals activate the enzymatic cascade resulting in the cleavage of protein substrates, leading to the disassembly of the cell. Caspases have been identified in organisms ranging fromC. eleganstoMembers of the mammalian caspase family of cysteinyl aspartate-specific proteases play distinct roles in apoptosis and inflammation.

Caspases
Active caspase enzymes exhibit catalytic and substrate specificities comprised of short tetra-peptide amino acid sequences that must contain an aspartate in the P1 position. These preferred tetra-peptide sequences have been used to derive peptides that specifically compete for caspase binding. In addition to the distinctive aspartate cleavage site at P1, the catalytic domains of the caspases typically require four amino acids to the left of the cleavage site with P4 as the prominent specificity-determining residue. Addition of a fluoromethyl ketone (FMK) to the tetrapeptide results in an irreversible linkage and permanent inactivation of the cysteine protease enzyme. Furthermore, conjugation of a fluorescent moiety at the amino terminus yields a probe that allows for the detection of caspase activity.

FLICA® 660 Caspase-3 Assay: Detection Mechanism

The far-red FLICA® 660-DEVD-FMK caspase-3 detection probe is comprised of the preferred affinity peptide sequence (DEVD) targeted by activated caspase-3 and caspase-7, a far-red fluorescent 660 dye label, and a fluoromethyl ketone (FMK) reactive moiety. The resulting fluorescent caspase-3 inhibitor probe forms an irreversible, covalent bond with active caspase-3 enzymes, efficiently labeling the target for detection. Due to its cell permeant nature and fluorescence properties, the far-red FLICA caspase-3 detection probe enables whole cell analysis via common fluorescence detection methods.

To use FLICA Caspase-3 Assay, add the caspase-3 detection probe directly to suspension cell or tissue culture media, incubate, and wash. The cell permeant, far-red FLICA caspase-3 detection probe will efficiently diffuse into cells and irreversibly bind to activated caspase-3 enzymes, thereby retaining the red signal inside caspase-3-positive cells. Cells not bearing active caspase-3 return to a non-fluorescent status after the wash step.

The FLICA® 660 caspase-3 detection probe has an optimal excitation at 660 nm and optimal emission range from 680-690 nm. As such, it has demonstrated excellent excitation efficiency with a conventional red HeNe laser with a 633 nm excitation, enabling samples to be analyzed with most flow cytometers and fluorescence microscopes equipped with electronic grey scale image capabilities. Cells labeled with the FLICA® caspase-3 detection probe may be read immediately or preserved for 16 hours using the fixative.
