SLPI Protein, Human (107a.a, sf9, His, solution)

Cat. No.: HY-P73414A
COA Handling Instructions

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 (107a.a, sf9, His, solution) is the recombinant human-derived SLPI protein, expressed by Sf9 insect cells, with N-6*His labeled tag. The total length of SLPI Protein, Human (107a.a, sf9, His, solution) is 107 a.a., with molecular weight of ~19 kDa.

Background

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
