Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32065) at 1/1,000 dilution was used in 5% NFDM/TBST at 4C overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.

Immunocytochemistry/ Immunofluorescence: B7-H4 Antibody (PSH03-65) [NBP3-32065]

Immunocytochemistry/ Immunofluorescence: B7-H4 Antibody (PSH03-65) [NBP3-32065] - Immunocytochemistry analysis of SK-Br-3 (positive) and HeLa (negative) labeling B7-H4 with Rabbit anti-B7-H4 antibody (NBP3-32065) at 1/1,000 dilution.

Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-B7-H4 antibody (NBP3-32065) at 1/1,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.

Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Background: B7-H4

B7H4 is a costimulatory protein which is reported to function as a negative regulator of T-cell mediated immunity. Although B7H4 binds an unknown receptor, it is thought to deliver an inhibitory signal to T-cells preventing their proliferation, cell cycle progression and interleukin-2 production. B7H4 deficient mice are only minimally affected, thus suggesting B7H4 is important in the fine tuning of the T-cell mediated immune response. B7H4 is expressed on activated T-cells, B-cells, monocytes and dendritic cells. Aberrant expression has been associated with cancers of the lung, breast and ovary in humans. B7H4 could be a useful prognostic marker in Renal Cell Carcinoma (RCC). There are three different isoforms.
