GPVI Protein, Mouse (HEK293, His)

Cat. No.: HY-P70180
COA Handling Instructions

GPVI Protein is a platelet membrane protein with a molecular weight of ~62 kDa that is a physiological collagen receptor. GPVI is present as a complex with the homodimeric Fc receptor y-chain. GPVI must form such a dimeric complex to exhibit high affinity binding to collagen. The GPVI-induced activation mechanism is initiated by tyrosine phosphorylation of the immunoreceptor tyrosine-based activation motif (ITAM) of the FcR gamma-chain, and then this signal is transduced to many related proteins, mainly by tyrosine phosphorylation. Interaction of platelets with collagen via the receptor GPVI results in platelet activation and adhesion. GPVI Protein, Mouse (HEK293, His) is the recombinant mouse-derived GPVI protein, expressed by HEK293 , with C-6*His labeled tag. The total length of GPVI Protein, Mouse (HEK293, His) is 244 a.a., with molecular weight of 40-60 kDa.

Description

GPVI Protein is a platelet membrane protein with a molecular weight of ~62 kDa that is a physiological collagen receptor. GPVI is present as a complex with the homodimeric Fc receptor y-chain. GPVI must form such a dimeric complex to exhibit high affinity binding to collagen. The GPVI-induced activation mechanism is initiated by tyrosine phosphorylation of the immunoreceptor tyrosine-based activation motif (ITAM) of the FcR gamma-chain, and then this signal is transduced to many related proteins, mainly by tyrosine phosphorylation. Interaction of platelets with collagen via the receptor GPVI results in platelet activation and adhesion[1][2][3]. GPVI Protein, Mouse (HEK293, His) is the recombinant mouse-derived GPVI protein, expressed by HEK293 , with C-6*His labeled tag. The total length of GPVI Protein, Mouse (HEK293, His) is 244 a.a., with molecular weight of 40-60 kDa.

Background

Interaction of platelets with collagen via the receptor GPVI results in platelet activation and adhesion--the processes that are essential for thrombus formation. On the platelet surface, GPVI is present as a complex with the homodimeric Fc receptor y-chain (FcRgamma with a possible stoichiometry of two GPVI molecules and one FcRgamma dimer). When collagen binds to GPVI, a platelet activation cascade is initiated by tyrosine phosphorylation of the immunoreceptor tyrosine-based activation motif of FcRgamma and this phosphorylation induces the formation of a large complex composed from many signal-transducing proteins. GPVI inhibitor would be able to inhibit thrombus formation but still not cause a significant bleeding tendency[1].
both collagen and GPVI are insoluble molecules. The extracellular domain of GPVI is soluble forms as follows: the monomeric form (GPVIex) and the dimeric form of GPVI fused with the human immunoglobulin Fc domain (GPVI-Fc2). Purified GPVIex strongly inhibited convulxin (Cvx)-induced platelet aggregation but only weakly inhibited that induced by collagen-related peptide. However, only GPVI-Fc2, and not GPVIex, inhibited collagen-induced platelet aggregation[3].

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

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
