| The antimicrobial protein BPI is a 55kD 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 airways 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 21kD 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. | | | Catalog # | B0003-40 | | Applications | Suitable for use in immunoassays both as coating and as detector. | | Recommended Dilutions | Optimal dilutions to be determined by the researcher. | | | | Storage and Stability: | | May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | | CAS Number | n/a | | Clone Type | Monoclonal | | Isotype | IgG1 | | Clone No | 9G128 | | Host | Mouse | | Source | Human | | Concentration | ~0.1mg/ml | | Form | Supplied as a liquid in PBS, 0.1% BSA, 0.02% sodium azide. | | Purity | Purified by Protein G affinity chromatography. | | Immunogen | Human BPI. | | Specificity | Recognizes full length human natural and recombinant Bactericidal Permeability Increasing protein (BPI). 3F9 recognizes only free BPI and does not interact with BPI that has formed a complex with LPS. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. | | Alternate names | CAP57 |
