AROTEC - Model ATB01 - Bactericidal/Permeability-Increasing Protein (BPI) - Brochure

The existence of autoantibodies to bactericidal/permeability-increasing protein (BPI) was first described when it was noticed that 11 of 51 sera that were cANCA positive in immunofluorescence, recognised a 57 kDa antimicrobial cationic protein known as CAP57 in both ELISA and Western blot.  It is now known that CAP57 and BPI are identical.
