PowerStem ESPro1 is an easy to use serum-free medium for cultivation of embryonic stem cells of mice (mES cells). These pluripotent cells are derived from blastocysts and they can be established to a permanent cell culture. After injection into blastocysts in chimeras, they can form all tissues, including germ cells. The mES cells largely maintain their undifferentiated state and can be integrated into the germ line.

Collagenases degrade native helical collagen fibrils. The enzyme has an important role in connective tissue metabolism and is produced by specific cells involved in repairs and remodelling processes. It is a type II enzyme that contains greater clostripain activity. It is generally used for heart, bone, muscle, thyroid, cartilage, and liver cells. Ca²⁺ is required for its activation while metal chelating agents such as cysteine, EDTA or o-phenanthroline inhibits its activity.

Ampicillin is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.

RNase-ExitusPlus™ is a non-alkaline, non-corrosive and non-carcinogenic cleansing solution that is highly active against RNase contamination. RNase-ExitusPlus™ has been demonstrated to inactivate more than 20 μg of RNase A dried onto the bottom of a microcentrifuge tube. RNase-ExitusPlus™ is stable for approximately 18 months and heat resistant. It should be stored at room temperature; at colder temperatures a precipitate may form which is easily brought into solution at 37 °C. RNase-ExitusPlus™ is supplied in spray bottles and a one litre refill pack is also available.

QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. The test strips are intended for single use, maintenance or calibration are not required.

Carboxymethyl Cellulose Sodium Salt is a high viscosity carboxymethylcellulose (CMC); the viscosity of a 1% solution in water at 25 °C is 1300-2200 centipoise (cps). The viscosity is both concentration and temperature dependent. As the temperaure increases, the viscosity decreases. As the concentration increases, the viscosity increases.

Cesium chloride, an inorganic compound, is an important source of cesium ions in a variety of applications. Its crystal structure forms a major structural type where each cesium ion is coordinated by 8 chlorine ions. Cesium chloride occurs naturally in mineral waters and as an impurity in carnallite (up to 0.002%), sylvite and kainite. Less than 20 tonnes of CsCl is produced annually worldwide, mostly from a cesium-bearing mineral pollucite.
