B7-H2/ICOSLG Protein, Human (Biotinylated, HEK293, His-Avi)

Cat. No.: HY-P78075
COA Handling Instructions

B7-H2/ICOSLG Protein, a ligand for T-cell receptor ICOS, critically costimulates T-cell proliferation and cytokine secretion. It induces B-cell proliferation and supports plasma cell differentiation, playing a key role in local tissue responses to inflammation. B7-H2/ICOSLG also modulates the secondary immune response by co-stimulating memory T-cell function. In molecular interactions, it has been observed to interact with CTLA4 in vitro. B7-H2/ICOSLG Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived B7-H2/ICOSLG protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Description

B7-H2/ICOSLG Protein, a ligand for T-cell receptor ICOS, critically costimulates T-cell proliferation and cytokine secretion. It induces B-cell proliferation and supports plasma cell differentiation, playing a key role in local tissue responses to inflammation. B7-H2/ICOSLG also modulates the secondary immune response by co-stimulating memory T-cell function. In molecular interactions, it has been observed to interact with CTLA4 in vitro. B7-H2/ICOSLG Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived B7-H2/ICOSLG protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Background

B7-H2/ICOSLG protein serves as a ligand for the T-cell-specific cell surface receptor ICOS, functioning as a critical costimulatory signal for T-cell proliferation and cytokine secretion. Additionally, it induces B-cell proliferation and facilitates their differentiation into plasma cells. This protein is poised to play a significant role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function. In molecular interactions, B7-H2/ICOSLG has been shown to interact with CTLA4 in vitro.

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • 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
