Azide-labeled B7-H4 Protein, Mouse (HEK293, His)

The B7-H4 protein acts as a negative regulator and inhibits T cell-mediated immune responses, including activation, proliferation, cytokine production, and cytotoxicity. Significant significance can be observed when expressed on tumor macrophages, cooperating with regulatory T cells (Tregs) to suppress tumor-associated antigen-specific T cell immunity. Azide-labeled B7-H4 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Azide-labeled B7-H4 protein, expressed by HEK293, with C-His labeled tag.

Biological Activity

Description

The B7-H4 protein acts as a negative regulator and inhibits T cell-mediated immune responses, including activation, proliferation, cytokine production, and cytotoxicity. Significant significance can be observed when expressed on tumor macrophages, cooperating with regulatory T cells (Tregs) to suppress tumor-associated antigen-specific T cell immunity. Azide-labeled B7-H4 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Azide-labeled B7-H4 protein, expressed by HEK293, with C-His labeled tag.

Background

B7-H4 protein serves as a negative regulator of the T-cell-mediated immune response by suppressing T-cell activation, proliferation, cytokine production, and the development of cytotoxicity. Its significance is particularly pronounced when expressed on the cell surface of tumor macrophages, where it collaborates with regulatory T-cells (Treg) to play a crucial role in suppressing tumor-associated antigen-specific T-cell immunity. Beyond its immunomodulatory functions, B7-H4 is also implicated in promoting epithelial cell transformation, highlighting its involvement in diverse cellular processes associated with immune regulation and tumorigenesis.

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 1 year from date of receipt, protect from light. 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.
