VISTA/B7-H5 Protein, Cynomolgus (HEK293, His)

Cat. No.: HY-P70962
Handling Instructions Technical Support

VISTA/B7-H5 Protein is a B7 family member that maintains T cell and myeloid quiescence and is a promising target for combination cancer immunotherapy. VISTA not only acts as a ligand expressed on antigenpresenting cells, but also functions as a receptor on T cells. VISTA inhibits T cell activation, proliferation, and cytokine production. VISTA/B7-H5 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived VISTA/B7-H5 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

V-domain immunoglobulin suppressor of T cell activation (VISTA) is a B7 family member that maintains T cell and myeloid quiescence and is a promising target for combination cancer immunotherapy. VISTA,a type I transmembrane protein, is primarily expressed in hematopoietic cells. VISTA activity reprograms macrophages towards reduced production of proinflammatory cytokines and increased production of interleukin (IL)-10 and other anti-inflammatory mediators. VISTA not only acts as a ligand expressed on antigenpresenting cells, but also functions as a receptor on T cells. VISTA is an immune checkpoint receptor expressed on tumor-infiltrating T lymphocytes (TILs) and myeloid cells, leading to suppression of T cell activation, proliferation, and cytokine production, thereby promoting immune evasion and survival in a variety of human cancers, such as prostate cancer, non-small cell lung cancer (NSCLC), and colorectal carcinoma. VISTA is overexpressed in tumor tissues and functions as a co-stimulatory molecule[1][2][3].

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)
× = ×

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
