Genomic PCR Grade Proteinase K Powder
Proteinase K s a broad-spectrum serine protease. The enzyme was discovered in 1974 in extracts of the fungus Engyodontium album (formerly Tritirachium album).Proteinase K is able to digest hair (keratin), hence, the name "Proteinase K". The predominant site of cleavage is the peptide bond adjacent to the carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups. It is commonly used for its broad specificity. This enzyme belongs to Peptidase family S8. The molecular weight of Proteinase K is 28,900 Daltons (28.9 kDa).
TAQ or Pfu or Pfx or other enzymes are used for polycmerase chain reaction and have different specificity. The mores specific the lower the yield.
Thermocyclers can be callibrated for identical ramping curves to obtain a more accurate PCR.
