抗 BPI (61-75) 兔抗

NA.41

BPI (Bactericidal permeability-increasing protein) gene is mapped on to human chromosome 20q11.23. It belongs to the family of lipid-transfer proteins. BPI is mainly present in the granules of neutrophils and on the surface of neutrophils and monocytes.

synthetic peptide corresponding to amino acids 61-75 of human BPI

Anti-BPI (61-75) antibody produced in rabbit has been used in immunoprecipitation.

BPI gene encodes a membrane associated bactericidal permeability increasing protein. BPI possesses high affinity for lipopolysaccharide. It has antimicrobial activity against gram-negative organisms and is essential constituent of the innate immune system for destroying the microbes as well as modulates subsequent adaptive immune responses. The amino-terminal of BPI is responsible for antimicrobial cytotoxicity and endotoxin-neutralization. The carboxyl-terminal is mainly for BPI-dependent transfer of Gram-negative bacteria and cell free endotoxin-rich particles to specific host cells. Mutation in BPI gene or a decrease of plasma BPI level may lead to chronic obstructive pulmonary disease (acute pneumonia and cystic fibrosis).
