The Mouse Anti-citrullinated COL2A1 Antibody clone ACC1 binds to the triple helical C1 epitope on collagen II when citrullinated. Binding to collagen II epitopes was determined in bead-based flow immunoassay as median fluorescence intensity (MFI).


Affinity purified mouse monoclonal anti collagen II (COL2A1) antibody clone ACC1 in PBS, sterile filtered (0.2 µm). The antibody binds to the citrullinated triple helical collagen type II (CII) epitope (position 359-369; ARGLTGRPGDA)1, the C1 epitope. The ACC1 antibody recognizes the second citrulline at position 365 in mouse CII1. The antibody binds to flexible triple-helical CII determinants as well as many citrullinated CII peptides and was found to cross-react with several non-citrullinated epitopes on native CII2. The antibody has been used in applications including ELISA1,2, immuno­histochemistry (IHC)1 and bead-based multiplex immunoassays2.

Target with alternative names: COL2A1, Collagen alpha-1(II) chain, CII, Col II, citrullinated CII; citrullinated Col II; citrullinated proteins. UniProt: P28481.

Immunogen: Bovine Collagen type II 1

Species reactivity: Mouse, human

Isotype:  Mouse IgG2a, κ

Specificity: ACC1 antibody binds the citrullinated C1 epitope. The ACC1 antibody cross-reacts with triple-helical epitopes on CII, but not with other collagens or the proteins tested in Ge et al2, except for a few citrullinated peptides.2

Concentration: 1 mg/ml

Supplied in: PBS

Storage: Centrifuge briefly prior to opening vial. Store at +4°C short term (1-2 weeks). Aliquot and store at -20°C long term. Avoid repeated freeze/thaw cycles.

Recommended dilution: It is recommended the user determines the optimal dilution for their application. The typical starting working dilutions are: IHC 1:100, ELISA 1:200 - 1:500.
