Molecular Structure
A soluble fusion protein consisting of the extracellular (224 aa) domain of human CD86 fused to murine IgG2a Fc region. This molecules contains 4 amino acid polymorphisms when compared to Genebank sequence HUMB72A: v(162)i, h(217)q, m(97)v, and h(90)r. Two of these, m(97)v, and h(90)r are present in the putative CD86-CD152 binding site(5).

Transfectant Cell Line
CHO
Performance
CD86(variant)-muIg was reactive in an Enzyme Immuno Assay utilizing a Goat anti-Mouse Ig coated plate for capture and anti-CD86/Biotin followed by Streptavidin/HRP and TMB/H2 O2 substrate chromagen for detection. This product exhibited a reduced affinity for CD152 in FACS and EIA as compared to CD86-muIg and CD86(p2)-muIg.
Production
Recombinant protein from (low FBS containing) tissue culture supernatant of transfectants was purified using affinity and size exclusion chromatography. Product was 0.2u sterile-filtered and vialed under aseptic conditions.
Buffer
50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl. Product was 0.1 um filtered and vialed under aseptic conditions.
Preparation and Storage
Store at 2 - 5 degree C. Open under aseptic conditions. Freeze/Thawing is not recommended.
Product should retain activity for at least 12 months after shipping date when stored as recommended.

NCBI Description

This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011]

Uniprot Description

CD86: Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T- cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation. 4 isoforms of the human protein are produced by alternative splicing.

Product Notes

The CD86 cd86 (Catalog #AAA666808) is a Protein produced from CHO cells and is intended for research purposes only. The product is available for immediate purchase. The CD86(var)-muIg-Purified Preservative Free reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's CD86 can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA). Researchers should empirically determine the suitability of the CD86 cd86 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CD86, Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
