Complement Factor D/Adipsin Protein, Rat (P.pastoris, His)

Customer Review

Based on 1 Customer Validation

Complement Factor D/Adipsin Protein is pivotal, cleaving factor B within the factor C3b complex to activate the C3bbb complex, serving as the C3 convertase in the alternate pathway—analogous to C1s in the classical pathway. Complement Factor D/Adipsin Protein, Rat (P.pastoris, His) is the recombinant rat-derived Complement Factor D/Adipsin protein, expressed by P. pastoris , with N-6*His labeled tag.

Biological Activity

Description

Complement Factor D/Adipsin Protein is pivotal, cleaving factor B within the factor C3b complex to activate the C3bbb complex, serving as the C3 convertase in the alternate pathway—analogous to C1s in the classical pathway. Complement Factor D/Adipsin Protein, Rat (P.pastoris, His) is the recombinant rat-derived Complement Factor D/Adipsin protein, expressed by P. pastoris , with N-6*His labeled tag.

Background

Complement Factor D/Adipsin Protein performs a crucial role by cleaving factor B when it is in complex with factor C3b. This cleavage triggers the activation of the C3bbb complex, subsequently forming the C3 convertase of the alternate pathway. Importantly, its function is analogous to that of C1s in the classical pathway.
