SLPI Protein, Human (HEK293, Fc)

SLPI Protein, an acid-stable proteinase inhibitor, demonstrates strong affinities for trypsin, chymotrypsin, elastase, and cathepsin G in various studies. It crucially modulates inflammatory and immune responses post-bacterial infection and L.major infection. SLPI down-regulates responses to bacterial lipopolysaccharide (LPS), regulates NF-kappa-B activation, impacting inflammatory responses. It exhibits antimicrobial activity against mycobacteria, contributing to resistance against M.tuberculosis. Essential for normal resistance to L.major infection, SLPI plays a vital role in wound healing, preventing tissue damage by regulating protease activity. Collaborating with ELANE, SLPI is necessary for normal bone marrow myeloid cell differentiation and proliferation, interacting with GRN to protect progranulin from proteolysis. SLPI Protein, Human (HEK293, Fc) is the recombinant human-derived SLPI protein, expressed by HEK293, with C-hFc labeled tag. The total length of SLPI Protein, Human (HEK293, Fc) is 107 a.a., with molecular weight of 40-50 kDa.

SLPI, an acid-stable proteinase inhibitor, exhibits robust affinities for trypsin, chymotrypsin, elastase, and cathepsin G, as demonstrated in various studies. It plays a crucial role in modulating inflammatory and immune responses following bacterial infection, as well as infection by the intracellular parasite L.major. Additionally, SLPI contributes to down-regulating responses to bacterial lipopolysaccharide (LPS) (By similarity) and is involved in regulating the activation of NF-kappa-B, thereby influencing inflammatory responses. Notably, SLPI exhibits antimicrobial activity against mycobacteria but not against salmonella, contributing to normal resistance against infection by M.tuberculosis. It is also essential for normal resistance to infection by L.major and plays a critical role in wound healing, likely by preventing tissue damage through the regulation of protease activity (By similarity). Furthermore, in collaboration with ELANE, SLPI is required for the normal differentiation and proliferation of bone marrow myeloid cells, and it interacts with GRN, protecting progranulin from proteolysis.
