Pure Enzymes for Starch Research

  • for complete debranching of starch and glycogen.
  • Ultrapure. Contaminating enzymes < 1 part in 106 (by activity).

Pullulanase (E-PULKP)

  • for partial but controlled debranching of starch.
  • Affinity purified. Contaminating enzymes < 1 part in 105 (by activity).

β-Amylase (barley) (E-BARBL)

  • removal of maltosyl units from the non-reducing ends of maltodextrin chains.
  • Recrystallised. Contaminating enzymes < 1 part in 106 (by activity).  

α-Amylase (B. amyloliquefaciens) (E-BAASS)
