Papain (1.5-10 units/mg)
Based on 1 Customer Validation
Papain (1.5-10 units/mg) is a cysteine protease of the peptidase C1 family. Papain (1.5-10 units/mg) enhances red cell agglutination by anti-D and anti-A, and increases red cell sensitivity to K cell-mediated lysis in ADCC assays. Papain (1.5-10 units/mg) can induce pulmonary emphysema. Papain (1.5-10 units/mg) can be used for the researches of Rh haemolytic disease of the newborn and pulmonary emphysema.

Biological Activity
Description
In Vitro
Papain (1.5-10 units/mg) (5 U/mL; 15 min) pretreatment of O Rh-positive red cells enhances anti-D-mediated agglutination, while it slightly reduces anti-A-mediated agglutination of A Rh-negative red cells[2].
Papain (1.5-10 units/mg) (5 U/mL; 15 min) pretreatment of O Rh-positive red cells increases their sensitivity to lymphocyte-mediated lysis in anti-D-mediated ADCC assays at low antibody concentrations and a 15:1 effector-to-target ratio[2].
Papain (1.5-10 units/mg) (5 U/mL; 15 min) pretreatment of O Rh-positive target red cells enables significant PBMC-mediated lysis in anti-D-mediated ADCC assays at a 1:3:3 effector-to-target-to-competitor ratio[2].
Papain (1.5-10 units/mg) (5 U/mL; 15 min) pretreatment of A Rh-negative target red cells enables significant PBMC-mediated lysis in anti-A-mediated ADCC assays at a 1:3:3 effector-to-target-to-competitor ratio[2].
