Human lung elastin (EPC No. HS395) labeled with the chromophore remazolbrilliant blue (RBB). The RBB is bound to elastin by ether linkage and is resistant to non-specific elution.
This substrate is useful for determination of specific elastolytic activity of human sputum elastase; see Methods.
This elastin is insoluble in biological buffers.
All human tissue donors are screened for the following:
Basic serology Panel #1 RPR Syphillis Serology, ABO/RH Typing HIV-1/HIV2 Antibody Screen, Hepatitis B Surface antigen, Hepatitis B Core IgG/Igm Antibody, HTLV-1 Antibody. We accept only donors that are non reactive to all of the above screening.
