Recombinant Human Human PIK3CB, His-tagged

• Cat.No.: PIK3CB-31766TH
• Product Overview: Recombinant full length Human PIK3CB with N-terminal His tag and recombinant full length Human PIK3R1, untagged, co expressed in a Baculovirus infected Sf9 cell expression system, 124 kDa,and 83kDa respectively.

Specification

• Description: Phosphoinositide 3-kinases (PI3Ks) phosphorylate the 3-prime OH position of the inositol ring of inositol lipids. They have been implicated as participants in signaling pathways regulating cell growth by virtue of their activation in response to various mitogenic stimuli. PI3Ks are composed of a 110-kD catalytic subunit, such as PIK3CB, and an 85-kD adaptor subunit (Hu et al.
