Popis: α-Chymotrypsin is a serine peptidase and has 241 amino acid residues contained in three polypeptide chains (A chain-13 residues, B chain-131 residues, and C chain-97 residues) linked by disulfide bridges. Molecular weight of this enzyme is found to be 25 kDa. Its pI is 8,75. It selectively hydrolyses peptide bonds on the C-terminal side of tyrosine, phenylalanine, tryptophan, and leucine. Ca²⁺ activates and stabilizes the enzyme. The enzyme is inhibited by diisopropyl fluorophosphate (DFP), phenylmethanesulfonyl fluoride (PMSF), N-p-tosyl-L-phenylalanine chloromethyl ketone (TPCK), chymostatin, aprotinin, α1-antitrypsin, α2-macroglobulin, 10 mM Cu²⁺ and Hg²⁺.A serine protease that hydrolyzes peptide bonds with aromatic or large hydrophobic side chains (Tyr, Trp, Phe, Met, Leu) on the carboxyl end of the bond.

Popis: Cloning cylinders, made of glass, light brown(tinted). Individual colonies of transfected cells can be isolated and picked from a plate containing many clones. Isolated clones can be dissociated and passaged free from surrounding cells or pulsed with 50 to 100 µl growth medium which can be analyzed for secreted products. The sterile cloning cylinders are greased on one end to allow the cylinder to seal to the plate. Cells are then dissociated within the cylinder, resuspeneded, and transferred to a new vessel as a pure colony.
