Immunofluorescence analysis of Aggrecan G3 was performed using 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Aggrecan G3 Rabbit Polyclonal Antibody (Product # PA1-1745) at 2 µg/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conj µgate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing localization in the extracellular matrix. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA1-1745 detects human, rat, mouse, bovine, and canine aggrecan G3.
PA1-1745 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~350 kDa protein representing the aggrecan G3 domain on the full length core.
The PA1-1745 immunogen is a synthetic peptide corresponding to residues C D(2277) G H P M Q F E N W R P N Q P D N(2293) of human aggrecan.. This antibody is also referred to as anti-G3.
Aggrecan is a member of large, aggregating proteoglycans (also including, versican, brevican and neurocan) 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 (MMP and quote;s) and aggrecanase. Aggrecan cleavage has been associated with a number of degenerative diseases including rheumatoid arthritis and osteoarthritis.
The G3 domain is a complicated region produced by alternative splicing of exons in post-transcriptional processes. The human G3 domain consists of three modules and articular cartilage contains a mixture of the alternatively spliced G3 modules. G3 has been shown to facilitate glycosaminoglycan (GAG) attachment and overall aggrecan processing. The G3 domain is central to aggrecan turnover and function in cartilage.
