Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human COLEC12 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Data

Function Scavenger receptor that displays several functions associated with host defense. Promotes binding and phagocytosis of Gram-positive, Gram-negative bacteria and yeast. Mediates the recognition, internalization and degradation of oxidatively modified low density lipoprotein (oxLDL) by vascular endothelial cells. Binds to several carbohydrates including Gal-type ligands, D-galactose, L- and D-fucose, GalNAc, T and Tn antigens in a calcium-dependent manner and internalizes specifically GalNAc in nurse-like cells. Binds also to sialyl Lewis X or a trisaccharide and asialo-orosomucoid (ASOR). May also play a role in the clearance of amyloid-beta in Alzheimer disease.
Gene References into Functions
  1. CL-P1 is a novel receptor involved in myelin uptake by phagocytes and likely plays a role in multiple sclerosis lesion development. PMID: 28317919
  2. rs17684886 (ZNRF1) and rs599019 (COLEC12) are associated with diabetic retinopathy and rs6427247 (SCYL1BP1) and rs899036 (API5) are associated with severe diabetic retinopathy in Chinese patients with type 2 diabetes PMID: 25819896
  3. The common presence of Lewis(x) groups in granule protein glycans can thus target granule proteins for clearance by SRCL. PMID: 21561871
  4. The Le(x) residues of both, CEACAM1 and CEA, interact with the human Le(x)-binding glycan receptors DC-SIGN and SRCL. PMID: 20034698
  5. haplotype structure of the CL-P1 gene obtained from six single-nucleotide polymorphisms that were genotyped with 108 alleles in Japanese subjects PMID: 12601552
  6. SRCL is expressed in some but not all nurse-like cells; its C-type lectin domain binds specifically to several carbohydrates including GalNAc, T and Tn antigen in a Ca2+-dependent manner. PMID: 12761161
  7. SRCL might be involved in selective clearance of specific desialylated glycoproteins from circulation and/or interaction of cells bearing Lewis(x)-type structures with the vascular endothelium PMID: 15845541
  8. CL-P1 is not a common membrane protein on endothelial cells found in normal tissues under steady state conditions. PMID: 18423602
  9. CL-P1 predominantly mediated phagocytosis for fungi in vascular endothelia. PMID: 19073604
