Background Information

COLEC11, also named as CL-K1 and Collectin-11, belongs to the COLEC10/COLEC11 family. It is a lectin that binds to various sugars: fucose > mannose. It does not bind to glucose, N-acetylglucosamine and N-acetylgalactosamine. COLEC11 binds to LPS. COLEC11 and MASP1 are two genes in the lectin complement pathway, they are mutated in 3MC syndrome, implicating this diverse inflammation-chemotaxis cascade in the etiology of human developmental disorders. COLEC11 serves as a guidance cue for neural crest cell migration.(PMID:21258343)

Christopher (Verified Customer) (08-28-2019)

Antibody works for identification of recombinant CL-11 well however multiple bands appears on cell lysates.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: Human PTECs

mark (Verified Customer) (08-13-2019)

Consitent fro WB but binds non CL-11 in cell lysatesFor immunohistochemistry/immunoflourescence binds CL-11 consistently but also has off target effects (eg in CL-11 KO mice)

  • Applications: Western Blot, Immunohistochemistry, Immunofluorescence,
  • Primary Antibody Dilution: 1:1000 for WB, 1:100 for Immuno
  • Cell Tissue Type: mouse cell culture, mouse kidney, mouse embryos, human kidney
