Western Blot (WB)

(Western blot analysis of extracts from mouse spleen, using CD28 Antibody.The lane on the right is treated with the antigen-specific peptide.)

Immunohistochemistry (IHC)

(MBS9600003 at 1/100 staining Human thyroid cancer tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)

Related Product Information for anti-CD28 antibody

Function: Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in conjunction with TCR/CD3 ligation and CD40L costimulation (PubMed:8617933). Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells (PubMed:15067037).
Subunit Structure: Homodimer; disulfide-linked. Interacts with DUSP14. Binds to CD80/B7-1 and CD86/B7-2/B70. Interacts with GRB2. Isoform 3 interacts with CD40LG (PubMed:15067037).
Post-translational Modifications: CD40LG induces tyrosine phosphorylation of isoform 3.

NCBI Description

The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]
