1:300 Solution. Used as a red nuclear counterstain in various cytochemical procedures.

Trypan Blue is a blue acid dye with a strong affinity for cellulose containing substrates such as cotton; less affinity for proteinaceous materials. Trypan blue solution may be used in trypan blue based cytotoxitiy and proliferation assays. Trypan Blue is used as a vital dye which is especially important because it is taken up by the reticuloendothelial system. Clark describes assays for the study of teratogenic action of trypan blue on embryonic tissues using Davis and Sauter's fluorescence method and for the staining of collagen, including very fine fibrils, muscle and cornified epithelium using the Van Gieson method. Trypan blue is also recommended for use in dye exclusion procedures for viable cell counting. Non-viable cells will up-take trypan blue at a faster rate than viable cells.

For use in the preparation of cell culture media, and cell suspension and washing solutions.

Hemoglobin is the major component of erythrocytes, and is responsible for the red color. Its normal concentration in erythrocytes is approximately 34%. It is the most important respiratory protein of vertebrates by virtue of its ability to transport oxygen to tissues and carries carbon dioxide away from the tissues. Anomalous globins in which various amino acids have been substitued with others, or in which certain amino acids are missing entirely from the normal sequence, comprise 153 abnormal hemoglobin configurations. Sickle cell anemia is one such configuration. In sickle cell hemoglobin, a valine residue has replaced the glutamic acid residue at position 6 in the b-chain of normal hemoglobin; the a-chain is normal.

HEPES (N-2-hydroxyethylpiperazine-N-2-ethane sulfonic acid) is a general purpose zwitterionic organic chemical buffering agent which does not bind magnesium, calcium, manganese(II) or copper (II) ions. Buffer strength for cell culture applications is usually in the range of 10 to 25 mM. Studies have indicated that 20 mM HEPES is the most satisfactory concentration of the buffer when both Hanks' and Earle's solutions are used.

(HCGS)
From Cultured Human Endothelial Cells
HCGS will significantly improve the hybridoma cell cloning efficiency while eliminating feeder cell need.
HCGS may be used in dilutions of 1:5 to 1:10 (v/v). We recommend HCGS be thawed and sterile filtered (0.22 or 0.45 membrane) immediately prior to use.

Human Interleukin-2 (IL-2), or Human T-cell growth factor is a glycoprotein which promotes in-vitro proliferation and long-term growth of T-cell lymphokines. Additionaly, IL-2 stimulates production of cytotoxic lymphocytes, natural killer cells, and lymphokine-activated killer cells.

L-glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.
