Aggrecan antibody | 7E1
Mouse anti Human aggrecan antibody, clone 7E1 (MCA1451G) used for the detection of aggrecan expressing cells in murine micromass cultures by immunocytochemistry.
Image caption:
Regulation of Extracellular matrix (ECM) composition by Bone morphogenetic protein (BMP) family growth factors during chondrogenesis. Mouse micromass cultures without treatment (A–E), Gdf-5 treatment (F–J), and Bmp-7 treatment (K–O); Alcian blue stain (A–K) showed cartilage nodules, Immunohistochemical stain for type 1 collagen (A, F, K), type II collagen (C, H, M), aggrecan (D, I, N), and fibronectin (E, J, O). Statistical analysis for histochemical and immunohistochemical data, (P) = percentage of positive area for Alcian blue, type I collagen, type II collagen, aggrecan, and fibronectin stains in micromasses with different treatments; mean values are shown with Standard deviations (SD) (n = three independent experiments), One-way Analysis of variance (ANOVA). ***P <0.0001; **p <0.001; *p <0.05). Gdf-5 mainly induces aggrecan expression, type II collagen, and fibronectin; aggrecan is an articular cartilage marker; in contrast, Bmp-7 induce type I collagen, an extracellular component of hypertrophic cartilage and bone.

Mouse anti Human aggrecan antibody, clone 7E1 recognizes human aggrecan, a proteoglycan and member of the aggrecan/versican proteoglycan family, which forms a major component of the extracellular matrix (ECM) of both cartilage and the central nervous system (CNS).
Studies using a panel of core protein-directed antibodies against human aggrecan, revealed the distribution of different aggrecan isoforms within the CNS, and sub-divided the isoforms into clusters 1-5 accordingly. These studies also showed a difference in the relative abundance of these isoforms when comparing brain and cartilage tissues (Virgintino et al. 2009).
Mouse anti Human aggrecan antibody, clone 7E1 recognizes a ~205 kDa trypsin derived fragment of aggrecan.
Note: Originally described as being of the isotype IgM, clone 7E1 was found to be unstable and was re-cloned by the originator and the new stable sub-clone was confirmed as being an IgG1.
