Product Description
Recombinant Guinea Pig TNF alpha
Recombinant Guinea Pig TNF alpha is primarily produced as a 212-amino acid-long type II transmembrane protein arranged in stable homotrimers. From this membrane-integrated form the soluble homotrimeric cytokine (sTNF) is released via proteolytic cleavage by the metalloprotease TNF alpha converting enzyme (TACE, also called ADAM17). The soluble 51 kDa trimeric sTNF tends to dissociate at concentrations below the nanomolar range, thereby losing its bioactivity. The secreted form of human TNF- takes on a triangular pyramid shape, and weighs around 17-kD. Both the secreted and the membrane bound forms are
BIOLOG
ically active, although the specific functions of each is controversial. But, both forms do have overlapping and distinct
BIOLOG
y activities.
