Trypsin-EDTA solution

Описание:

Trypsin consists of a single-chain polypeptide of 223 amino acid residues, produced by the removal of the N-terminal hexapeptide from trypsinogen which is cleaved at the Lys — lle peptide bond. The sequence of amino acids is cross-linked by 6 disulfide bridges. This is the native form of trypsin, beta-trypsin. BETA-trypsin can be autolyzed, cleaving at the Lys — Ser residue, to produce alpha-trypsin. Trypsin is a member of the serine protease family.

Применение:

The typical use for this product is in removing adherent cells from a culture surface. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the culture. Trypsin-EDTA solution was used:in detaching HT29 human colorectal cancer cells cultured in RPMI 1640 which was supplemented with 10 % fetal calf serum, during relative cell frequency determination of high concentration samples.to trypsinize the transient transfected human embryonic kidney tcA-201 cell line.to enzymatically release mouse fibroblasts cells (cell line L929) adhered to the scaffold, during cell culturing to assess the influence of several modified treatments of Poly(L/D)lactide 96/4 non-woven scaffolds and fibres.to dissociate cells from the culture dish for flow cytometry analysis.Suitable for use in the preparation of single cell suspension for sequencing.
