A. A20079E_PURE_CD276_IHCP_070723
IHC staining of purified anti-CD276 (B7-H3) (clone A20079E) on formalin-fixed paraffin-embedded human tonsil tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., 1x (Cat. No. 928502), the tissue was incubated without (panel A) and with (panel B) 5 µg/mL of primary antibody followed by incubation with Alexa Fluor® 647 goat anti-mouse IgG (Cat. No. 405322) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured in an Olympus IX83 Inverted Microscope with a 20X objective. Scale bar: 50 µm

    ICC staining of purified anti-CD276 (B7-H3) (clone A20079E ) on HaCaT cells. The cells were fixed and permeabilized with ice-cold MeOH, then blocked with 5% FBS for 1 hour at room temperature. The cells were then stained with either 5 µg/mL of purified mouse IgG1, κ isotype control (Cat. No. 401402) (panel A) or 1.25 µg/mL of the primary antibody (panel B) overnight at 4°C, followed by incubation with 2.5 µg/mL of Alexa Fluor® 594 goat anti-mouse IgG (Cat. No. 405326) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801), and the images were captured with a 60X objective. Scale: 50 µm

    Whole cell extracts (15 µg total protein) from the indicated cell lines were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with 1 µg/mL of purified anti-CD276 (B7-H3) (clone A20079E ) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

Description

CD276, or B7-H3, is a type I transmembrane protein and shares 20-27% amino acid identity with other B7 family members. Human CD276 has a single extracellular variable-type immunoglobulin (IgV)-IgC domain and a signature intracellular domain. There also exists an additional isoform known as 4Ig-B7-H3, containing a nearly exact tandem duplication of the IgV-IgC domain. Expression of CD276 is induced on T cells, natural killer (NK) cells, and antigen-presenting cells (APCs), including dendritic cells (DCs) and macrophages, and is upregulated during the maturation of monocytes to DCs, or following interactions between DCs and regulatory T cells. CD276 inhibits T-cell responses, and plays a role in adaptive immunity by suppressing T cell activation. CD276 is also expressed in various cancers, where it works to suppress tumor antigen-specific immune responses.

Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 10.0 µg/mL is suggested. For flow cytometric staining, the suggested use of this reagent is ≤ 0.03 µg per million cells in 100 µL volume. For immunocytochemistry, a concentration range of 1.25 - 5.0 μg/mL is recommended. For western blotting, the suggested use of this reagent is 0.25 - 1.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.
