ADVANCED GASOTRANSMITTER INCUBATION

Carbon monoxide and nitric oxide are both important gasotransmitters with a wide variety of similar, overlapping, and different functions. Now it is possible to study them independently or simultaneously in cell culture without the difficulty of chemical donors. The OxyCycler GT4181CN is the only dual gasotransmitter cell culture system providing control of both CO and NO. It creates the ultimate incubator accessory when controlling CO and/or NO in a subchamber culture system.

UNLIMITED PROGRAMMED, DYNAMIC EXPOSURES

Consisting of a GT41 which provides the common O2, CO2, and RH control, and the modular GT81CN piggyback controller, which provides not only the CO and NO range control but also NO2 limiting, the combo can create virtually any type of dynamic or static exposure your cells might need.

MODULAR FLEXIBILITY

The controller is compatible and will fit any standard size C-Chamber. The entire OxyCycler GT4181CN CO/NO cell culture system will fit any existing incubator.

Installation Schematic

OxyCycler GT4181CN Culture System. Controls dynamic or static O2, CO2, CO and NO, and limits RH and NO2 in subchamber. Supply gases to GT41 required: Oxygen, Nitrogen, Carbon Dioxide. Calibration gas to GT41 required: certified pre-mix of 10% CO2 in balance oxygen. Supply gases to GT81CN: non-certified pre-mix of 10000ppm CO in balance nitrogen, and non-certified pre-mix of 1000ppm NO in balance nitrogen. Calibration gases to GT81CN required: certified pre-mix of 300ppm CO in balance nitrogen, certified pre-mix of 30ppm NO in balance nitrogen, and certified pre-mix 10ppm NO2 in balance nitrogen.

Configuration

The OxyCycler GT4181CN is a combination controller consisting of a GT41 mother controller and the GT81CN piggyback controller working in tandem. It is the ultimate for CO and NO gasotransmitter research. The GT41 controls core O2 and CO2 levels in dynamic or static states and limits RH, while the GT81CN controls 0-400 ppm CO in dynamic or static exposures, and 0-40 ppm NO in dynamic or static exposures, while limiting NO2 from accumulating past critical levels.

How It Works

Hot swap multipod adapter plate provides microbial barrier filters between cells culturing in the subchamber and all of the sensors and mechanisms that control O2, CO2, RH, CO, NO/NO2 and temperature. Hot swap multipods provide upgrade flexibility and immediate, easy maintenance. A pump draws a sample from the controlled atmosphere and passes by all sensors and returns to chamber through disposable microbial barrier filters. Appropriate gases are infused as necessary by controllers through terminal, microbial barrier filters. Small fan homogenizes gases throughout chamber and can be easily removed, sterilized and replaced.

Controller sits outside the incubator and umbilicals extend through port hole on the incubator and connect to Hot Swap Minipod Assembly inside the incubator.

Operated by a computer and powerful software allows user to program any type of exposure with all variables and repeat those exposures with the click of a mouse. Profiles can be created, stored and recorded 24 hrs a day/7 days a week.

Hypoxic stress can model components of many severe diseases such as heart attacks, strokes, asthma, or epilepsy. Frequency, duration and degree of drops are all adjustable.

Model step reduction in oxygen, similar to altitude acclimation, to gradually condition cells for hypoxic upregulation of gene expression. The rate of change between any two levels is adjustable and repeatable. The duration at any given level is adjustable and repeatable.

Cells destined for implantation will experience hypoxia and may be better prepared if they are conditioned to it before implantation. Ischemia may also be protected by conditioning. The OxyCycler GT4181CN can easily run any preconditioning profile.

Sudden increases in oxygen can cause cell damage. The OxyCycler GT4181CN allows modeling toxicity of oxygen in any cell culture, similar to toxicity from recreational oxygen inhalation by athletes, therapeutic oxygen administration in critical care units, and other sudden exposures to high oxygen. The rate of oxygen increase can be adjusted to change faster to overwhelm antioxidants, or change slower to condition for antioxidants.
