BPI, Human, ELISA Kit
- Supplier: Hycult Biotech
Product Description
- The antimicrobial protein BPI (Bactericidal Permeability Increasing protein) is a 55 kDa protein found in the primary (azurophilic) granules of human neutrophils and has also been detected on surface of neutrophils, small intestinal and oral epithelial cells. BPI is a bactericidal compound that is present in polymorphonuclear cells (PMN) and in lower levels in the specific granules of eosinophils. BPI possesses high affinity toward the lipid A region of lipopolysaccharides (LPS) that comprise the outer leaflet of the gram-negative bacterial outer membrane. Binding of BPI to the lipid A moiety of LPS exerts multiple anti-infective activities against gram-negative bacteria: 1) cytotoxicity via sequential damage to bacterial outer and inner lipid membranes, 2) neutralization of gram-negative bacterial LPS, 3) opsonization of bacteria to enhance phagocytosis by neutrophils. Airway epithelial cells constitutively express the BPI gene and produce the BPI protein and, therefore, BPI may be a critical determinant in the development of LPS-triggered airway disease. Inflammation induced by LPS possibly contributes to the development of rapid airflow decline, a serious and often fatal complication of hematopoietic cell transplantation. Furthermore, a 21 kDa bioactive recombinant fragment of BPI, rBPI21, was shown to confer a survival advantage against invasive pneumococcal disease by binding to the gram-positive bacterial pathogen, pneumolysin. In plasma of healthy individuals BPI is present at levels of < 0.5 ng/ml, which increases approximately 10-fold during acute phase responses.
- The human BPI ELISA kit has been developed for the quantitative measurement of natural and recombinant human BPI in culture medium, plasma, wound fluid and broncheoalveolar lavage fluid. In plasma samples human BPI can be measured accurately if plasma samples are diluted at least 4 times.
