Western Blot (WB)

(Western Blot analysis in MDA-MB453, CEM, HL-60, MDA-MB231 cell line lysates (35ug/lane) usingMBS642929. This demonstrates that MBS642929 detected the HHLA2 protein (arrow).)

Testing Data

(All lanes: MBS642929 (1:2000) Lane 1: human pancreas lysate Lane 2: MDA-MB-453 whole cell lysate Lysates/proteins at 20ug/lane. Secondary: IgG (HRP) Goat Anti-Rabbit. Predicted band size: 47kD Blocking/Dilution buffer: 5% NFDM/TBST.)

Immunohistochemistry (IHC)

(Immunohistochemistry analysis in formalin fixed and paraffin embedded human colon carcinoma using MBS642929 followed by peroxidase conjugation of the secondary antibody and DAB staining. This data demonstrates the use of MBS642929 for immunohistochemistry.)

Immunohistochemistry (IHC)

(Immunohistochemistry (FFPE) analysis of HHLA2 in human pancreas tissue sections usingMBS642929. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hours at RT; antigen retrieval was by heat mediation with a citrate buffer (pH 6). Samples were incubated with MBS642929 (1:25) for 1 hour at 37 degree C. A undiluted biotinylated goat polyvalent antibody was used as the secondary antibody.)

NCBI Description

This gene encodes a protein ligand found on the surface of monocytes. The encoded protein is thought to regulate cell-mediated immunity by binding to a receptor on T lymphocytes and inhibiting the proliferation of these cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

Uniprot Description

HHLA2: Through interaction with TMIGD2, costimulates T-cells in the context of TCR-mediated activation. Enhances T-cell proliferation and cytokine production via an AKT-dependent signaling cascade. Up-regulated in antigen-presenting cells in response to inflammation. Induced in dendritic cells in response to IFNG, poly(I:C) or heat-killed Listeria monocytogenes (at protein level). Interacts with TMIGD2. 2 isoforms of the human protein are produced by alternative splicing

Protein type: Membrane protein, integral

Chromosomal Location of Human Ortholog: 3q13.13

Cellular Component: integral to membrane

Molecular Function: protein binding

Biological Process: positive regulation of cytokine production; T cell costimulation; positive regulation of activated T cell proliferation
