Cell Culture Reagents

Phenol red is used as a pH indicator. The sodium salt of phenol red is used widely in culture media to identify changes from neutral to acidic pH values. A solution of phenol red will have a yellow color at a pH of 6.4 or below and a red color at a pH of 8.2 and above.

Lymphosep is designed for the simple, rapid isolation of lymphocytes from whole blood that has been diluted and treated with anti-coagulant or defibrinating agent.

L-Glutamine is an essential amino acid required by virtually all mammalian and insect cells grown in culture. It is a crucial component of many cell culture media and serves as a major energy source for cells in culture.

L-Glutamine is very stable as a dry powder and as a frozen solution. However, in liquid media or stock solutions, L-Glutamine can degrade relatively rapidly. L-Glutamine is also more labile in cell culture solution than other amino acids. 

This product is suitable to dissolve cell culture media in powder following the media technical data sheet.

Trypan Blue is a stain used to distinguish viable from not viable cells.

Trypsin is a porcine pancreas-derived enzyme that is commonly used for the dissociation and disaggregation of anchorage-dependent mammalian cells and tissues. The concentration of trypsin necessary to dislodge the cells from their substrate depends on the sensitivity of the cells.

D-glucose monohydrate is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. It is involved in a detrimental process in cells called glycation. It is used as a supplement for cell culture and in numerous cellular processes.

Phytohaemagglutinin is a lectin extracted from red kidney beans (Phaseolus vulgaris).

PHA-M is the mucoprotein form and is a crude extract used for the stimulation of cell proliferation in lymphocyte culture.

PHA-M also has a powerful erythroagglutinating property and it was originally used for separating leukocytes from whole blood.

Accutase is a ready to use cell detachment solution of proteolytic and collagenolytic enzymes.
Accutase is the "gentler form" of trypsin. It can replace Trypsin/EDTA for the detachment and dissociation of anchorage-dependent cells from surfaces. It can also be used on suspension cells to reduce clumping in preparation for counting.

Colcemid arrested the division of cells in mitosis. It prevents the formation of the spindle apparatus responsible for cell division, thereby permitting an accumulation of metaphases.
