Description: The 9B4 antibody reacts with human MD-2, an approximately 30 kDa molecule, which physically associates with the extracellular domain of TLR4. MD-2 is essential for correct intracellular distribution and LPS-recognition of TLR4 since in MD-2(-/-) embryonic fibroblasts, TLR4 was not able to reach the plasma membrane and predominantly resided in the Golgi apparatus, whereas TLR4 was distributed at the leading edge surface of cells in wild-type embryonic fibroblasts. MD-2(-/-) mice do not respond to LPS, do survive endotoxic shock but are susceptible to Salmonella typhimurium infection.
Applications Reported: The 9B4 antibody has been reported for use in immunoprecipitation.
Applications Tested: This 9B4 antibody has been tested by immunoprecipitation of recombinant MD-2 from cell supernatant. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
MD-2 is a gene that encodes a protein involved in the recognition of bacterial lipopolysaccharides (LPS) by the immune system. It is located on chromosome 8 and is part of a larger family of genes that encode for similar proteins. The MD-2 protein forms a complex with Toll-like receptor 4 (TLR4) to recognize and respond to LPS, triggering an immune response. Mutations or variations in the MD-2 gene have been associated with various diseases and conditions, including sepsis and inflammatory disorders.
