  • 相关性
    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.

  • ab3778 at 1/100 staining human articular cartilage by IHC-P. The tissue was formaldehyde fixed and blocked with a serum free protein block. An enzymatic antigen retrieval step was performed and the tissue was then incubated with the antibody for 1 hour. An HRP conjugated goat polyclonal antibody was used as the secondary.

  • Immunofluorescence analysis of Human articular chondrocytes, staining Aggrecan with ab3778.

    Cells were fixed with paraformaldehyde and blocked with 1% BSA for 1 hour. Cells were incubated with primary antibody overnight at 4°C. An AlexaFluor®488-conjugated rabbit anti-mouse IgG was used as the secondary antibody.
  • ab3778 used at a 1/50 dilution staining Aggrecan in human umbilical cord matrix mesenchymal stromal cells by Immunocytochemistry/ Immunofluorescence.
    Frozen sections of the 3D constructs (10µm) (n=2) were rehydrated with PBS for 5 minutes, and endogenous peroxidase activity was inhibited using 1% hydrogen peroxide in methanol for 30 minutes. The sections were then blocked in 3% horse serum for 20 minutes and incubated with a primary antibody, ab3778, for 1 hour at a 1/50 dilution. After primary antibody incubation the sections were incubated with a streptavidin linked horse anti-mouse IgG secondary antibody for 30 minutes. After secondary antibody incubation, the sections were incubated with avidin-biotinylated enzyme complex for 30 minutes, and then VIP substrate (purple color) was applied on sections for 4 minutes.

    The image shown is at 4 weeks, 25M.

Sorry but we don't have a standard ELISA procedure for use with this antibody. However I would recommend using an indirect ELISA approach. This is outlined here

Thank you for contacting us.

Unfortunately the indicated primary antibodies have not been tested with Flow Cytometry, and therefore are not covered by our Abpromise guarantee.

I would instead recommend using a different antibody aga...
