TIGIT Protein, Human (HEK293, Fc)

Cat. No.: HY-P7414
Handling Instructions

TIGIT Protein, Human (HEK293, Fc) produced in HEK293 cells is a polypeptide chain containing 352 amino acids with the C-termimal human IgG1 Fc fragment. T-cell immunoreceptor with Ig and ITIM domains (TIGIT) is also known as V-set and immunoglobulin domain-containing protein 9 (VSIG9), V-set and transmembrane domain-containing protein 3 (VSTM3). It belongs to single-pass type I membrane protein containing an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM).

T cell Ig and ITIM domain (TIGIT) is a transmembrane glycoprotein belonging to a poliovirus receptor family of type 1 proteins that also binds to CD155 and CD112 ligands. TIGIT is expressed on peripheral memory and regulatory CD4+ T cells and NK cells and is upregulated following activation on naive CD4+ T cells. CD155 is a high-affinity receptor for TIGIT expressed on monocytes and CD11c+ human dendritic cells (DCs). TIGIT contains an Ig-like V-type domain and an ITIM in its cytoplasmic domain, suggesting that receptor occupancy may trigger a negative signaling event[1].

  • Dilution 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)
