Specificity: Monoclonal Ab 2E2/B5 is specific for a core protein epitope of a human small basement membrane heparan sulfate proteoglycan (HS-PG). mAb 2E2/B5 recognizes an epitope different from that recognized by mAb 1F10/B8 and mAb 2H7/G11. Whereas previously perlecan was the only known basement membrane HS-PG, there is now evidence that at least two other basement membrane HS-PG exist: Agrin, originally discovered as an important component of the neuromuscular junction, and a novel small HS-PG which was isolated from human aorta and kidney. This HS-PG, with a molecular weight of 80-200 kDa (aorta) and 30-160 kDa (kidney) and a core protein size of 24 kDa or 22 kDa, respectively, was localized by immunohistochemistry to the basement membrane. Amino acid sequence analysis of tryptic peptides indicate, that this small HS-PG is clearly distinct from perlecan and agrin.
