Mouse Anti col2A1 Antibody (M2139)
cat#10110
 

Affinity purified mouse monoclonal anti collagen II (COL2A1) antibody clone M2139 in PBS, sterile filtered (20 µm). The antibody recognizes the J1 epitope on triple helical collagen II¹. The J1 epitope on mouse collagen consist of residues 551–564 with sequence MPGERRGAAGIAGPK^1,4. The antibody M2139 has been used in applications including immunohistochemistry⁴, Western blot², immunoprecipitation³, and in vivo⁴ and in vitro⁵ functional assays.
