Trypsin-EDTA Solution 1X

Trypsin is a serine protease derived from porcine pancreas. It is a single chain polypeptide of 223 amino acid residue with substrate specificity based on positively charged Lysine and Arginine side chains. Trypsin predominantly cleaves peptide chains at the carboxyl sides of Lysine and Arginine, except when either is followed by Proline. It is most commonly used for dissociation and disaggregation of adherent cells. Ethylenediaminetetraacetic acid (EDTA), a chelating agent is often added to enhance enzymatic activity of trypsin solution. EDTA acts by neutralizing calcium and magnesium ions that enhance cell to cell adhesion. This prroduct is a trypsin-EDTA solution formulated to contain 500BAEE units of porcine trypsin and 180ug EDTA tetrasodium salt per ml in Dulbecco's Phosphate Buffered Saline. It does not contain calcium, magnesium and phenol red.
