• Product name
  • Description
    Rabbit polyclonal to Aggrecan
  • Specificity
    ab53731 detects endogenous levels of fragment of activated Aggrecan resulting from cleavage adjacent to Asp369. It reacts with a cleaved (N-part) form of Aggrecan when it is cleaved at D369 of human aggrecan and at D369 of rat aggrecan. It will not react with full protein. The immunogen peptide is located at the C-term of the cleaved form.

  • Relevance
    Aggrecan is a member of a family of large, aggregating proteoglycans (also including versican, brevican and neurocan) which is found in articular cartilage. Aggrecan is composed of three major domains: G1, G2, and G3. Between the G1 and G2 domains there is an interglobulin region (IGD). The IGD region is the major site of cleavage by specific proteases like metalloproteinases (MMPs) and aggrecanase. Aggrecan cleavage has been associated with a number of degenerative diseases including rheumatoid arthritis and osteoarthritis. There is evidence that this family of proteoglycans modulates cell adhesion, migration, and axonal outgrowth in the CNS.

  • All lanes : Anti-Aggrecan antibody (ab53731) at 1/500 dilution

    Lane 1 : Jurkat cell extracts treated with Etoposide (25µM, 60mins)
    Lane 2 : Jurkat cell extracts treated with Etoposide (25µM, 60mins) with immunising peptide

    Predicted band size : 250 kDa
    Observed band size : 97 kDa (why is the actual band size different from the predicted?)
    Note: the observed band size may be smaller than predicted because this antibody detects endogenous levels of a fragment of activated Aggrecan.
