Kit contents scale proportionally with size, except sealing tape.
Example: The V1 kit contains 5X the listed quantities above, but will exclude the sealing tape.

For the “C” and “V” kits, the supplied 96-well strip plate consists of twelve 8-well strips in a support frame. This enables custom plate configurations.

Description

The rapid protocol (RP) PathScan® RP Total B7-H4 Sandwich ELISA Kit Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of B7-H4 protein in a reduced assay time of 1.5 hours. Incubation of cell lysate and detection antibody on the coated microwell plate forms a sandwich with B7-H4 protein in a single step. The plate is then extensively washed and TMB reagent is added for signal development. The magnitude of absorbance for the developed color is proportional to the quantity of B7-H4 protein.

*Antibodies in this kit are custom formulations specific to the kit.

Specificity/Sensitivity

PathScan® RP Total B7-H4 Sandwich ELISA Kit detects endogenous levels of B7-H4 protein and This kit sensitivity is shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

B7 homolog 4 (B7-H4, VTCN1) is a member of the B7 family of cell surface ligands that regulate T cell activation and immune responses (1-3). B7-H4 protein contains two extracellular Ig-like V-type domains, a transmembrane domain, and a short, two amino acid intracellular domain (3). The B7-H4 protein is shown to inhibit T cell activation, proliferation, and cytokine production (1,4,5). Although B7-H4 mRNA is widely expressed, B7-H4 protein is restricted to antigen-presenting cells and B cells (1). The B7-H4 protein is also found in several tumor types, including ovarian cancer and breast cancer (6). Research studies indicate that B7-H4 protein is present on the surface of ovarian tumor cells, and that targeted inhibition of B7-H4 using recombinant antibodies restores T cell activation pathways. These studies suggest some potential therapeutic value in blocking B7-H4 function and restoring T cell function in cancer patients (7,8).
