Calcium Chloride is a salt of calcium and chloride. It behaves as a typical ionic halide, and is solid at room temperature.
Calcium chloride is a commonly used reagent in biochemistry. It plays important roles in many biological processes, including signal transduction, muscle contraction, and maintenance of cell membrane and cell wall stability. Calcium chloride is used in the preparation and transformation of competent E. coli and in the transfection of eukaryotic cells with either plasmid DNA or high molecular weight genomic DNA. It has been used in the stabilization and two dimensional crystallization of the NADH-ubiquinone oxidoreductase (complex I) from Escherichia coli. It is also used as a dessicant, coagulant in rubber manufacturing and as an accelerator in the concrete industry.

Succinic acid is a dicarboxylic acid that occurs in nature in such organisms as fungi and lichens. In eukaryotes, succiniate, the anion of succinic acid, is an intermediate in the citric acid cycle, being formed from succinyl CoA and being converted to fumarate. Bacteria and plants can produce succinate from acetate or acetyl CoA, in the glyoxylate cycle.

Preparation Method: MP Intrinsic Factor is produced from the pylorus mucous membrane of the pig, of which only a small part is used. Only the part which, according to histological examinations has proved to have a high content of Intrinsic Factor, is used.
Applications: Intrinsic Factor is used in the treatment not only of classical pernicious anaemia, but also in the treatment of other macrocytic anaemias, where it replaces the Intrinsic Factor which may be lacking in the patient's own gastric juice. In this way Intrinsic Factor is recommended against anaemias that appear 6 to 12 months after serious gastric operations, and against anaemias that are secondary effects of the treatment with certain medicines, e.g. against epilepsy. However, the dietetic use in multi-vitamin preparations is of the greatest importance. In older people there has been observed a degeneration of the gastric mucous membrane, whose secretion of Intrinsic Factor is insufficient to ensure the resorption of the necessary quantity of B-12 from their diet. In order to delay this development it is useful to prescribe a small quantity of Intrinsic Factor with B-12 and other vitamins to these patients.
Product Description: Intrinsic factor is a glucoprotein extracted from the pylorus part of the gastric mucous membrane. Its presence is considered necessary for the absorption of Vitamin B-12.
Unit Definition: The activity is normally indicated in Coli units, the number of which are proportional to the binding power of the substance to Vitamin B-12.

Application Areas: Absorption of vitamin B12
Product Type: Proteins, Enzymes & Peptides
Presentation: Tan Powder
Foreign activity: Salmonella=Negative, E. coli=Negative
NOTES: Standard Plate Count <1000/g
Solubility: Slightly soluble in toluene; practically insoluble in water.

3-(4,5-Dimethylthiazolyl-2)-2,5-Diphenyl Tetrazolium Bromide(MTT) is an histochemical/cytochemical reagent. It is converted to water-insoluble MTT-formazan of dark blue color by mitochondrial dehydrogenases of living cells, thus used for measurement of cell division.

2,3,5-Triphenyltetrazolium Chloride is a redox indicator. In the TTC assay (also known as TTC test or tetrazolium test), TTC is used to differentiate between metabolically active and inactive tissues. The white compound is enzymatically reduced to red TPF (1,3,5-triphenylformazan) in living tissues due to the activity of various dehydrogenases (enzymes important in oxidation of organic compounds and thus cellular metabolism), while it remains as white TTC in areas of necrosis since these enzymes have been either denatured or degraded.
2,3,5-Triphenyltetrazolium Chloride is commonly used in biochemical experiments especially to indicate cellular respiration. TTC has been employed in autopsy pathology to assist identification of post-mortem myocardial infarctions. Healthy viable heart muscle will stain deep red from the cardiac lactate dehydrogenase; while areas of potential infarctions will be more pale. Useful indicator for reducing substances
