Description

SIRP alpha/CD172a Protein, Human (P78324, HEK293, His) is a polypeptide chain amino acids with the C-termimal His tag. Signal regulatory protein alpha (SIRPα, designated CD172a) is a monomeric about 90kDa type I transmembrane glycoprotein that belongs to the SIRP/SHPS (CD172) family of the immunoglobulin superfamily.

Background

Signal regulatory protein α (SIRPα) is a glycoprotein receptor that recruits and signals via the tyrosine phosphatases SHP-1 and SHP-2.The cytoplasmic domain of SIRPα contains four immunoreceptor tyrosine-based inhibition motifs (ITIMs), which upon phosphorylation recruit and activate SH2-domain-containing phosphotyrosine phosphatases (PTPase) SHP-1 and SHP-2. In macrophages SIRPα can negatively regulate the phagocytosis of host cells and the production of tumor necrosis factor alpha. SIRPα ligation induces macrophage NO production through the cooperative action of JAK/STAT and PI3-K/Rac1/NOX/H2O2 signaling pathways. It proposes that SIRPα may function as an inhibitory receptor[1].

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.

  • Specific Activity Calculator

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)
× = ×
C1   V1   C2   V2

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
