Mouse CL-P1/COLEC12 Antibody Summary

Species Reactivity
Detects mouse CL‑P1/COLEC12 in direct ELISAs and Western blots.
Polyclonal Goat IgG
Antigen Affinity-purified
Mouse myeloma cell line NS0-derived recombinant mouse CL‑P1/COLEC12
Accession # Q8K4Q8
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
0.1 µg/mL
Recombinant Mouse CL-P1/COLEC12 (Catalog # 3130-CL)
Flow Cytometry
2.5 µg/106 cells
See below
Blockade of Receptor-ligand Interaction
In a functional ELISA, 1-4 µg/mL of this antibody will block 50% of the binding of 100 ng/mL of biotinylated AGE‑BSA to immobilized Recombinant Mouse CL-P1/COLEC12 (Catalog # 3130-CL) coated at 5 µg/mL (100 µL/well). At 100 μg/mL, this antibody will block >90% of the binding.
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: CL-P1/COLEC12

Collectins are a family of Ca++-dependent, C-type lectins that contain a collagenous domain and function as recognition molecules for molecular patterns found on pathogens (1‑4). Collectin placenta 1 (CL-P1), also known as collectin sub-family member 12 and scavenger receptor with C-type lectin type I (SRCL), is a 140 kDa member of the collectin family of glycoproteins. With two exceptions, all collectins are secreted. CL-P1 is the only collectin known to be membrane bound, while CL‑L1 (collectin liver-1) is the only known cytoplasmic collectin (1). Mouse CL-P1 is synthesized as a 742 amino acid (aa) type II transmembrane glycoprotein that includes an N-terminal 39 aa cytoplasmic domain, an 18 aa transmembrane segment, and a 685 aa C-terminal extracellular domain. The short cytoplasmic domain contains an internalization motif (Y-K-R-F), while the ECD is complex, demonstrating a coiled-coil segment, a Ser-Thr rich region, a collagen-like structure, and a C‑type lectin/carbohydrate recognition domain (CRD) (5, 6). Unlike human CL-P1, no splice variants of mouse CL-P1 have been described (5, 7). Trimerization of CL‑P1 is mediated by its collagen-like and coiled-coil helical domains (1, 6). Within the ECD, mouse CL-P1 shares 88%, 89%, 92%, and 98% aa sequence identity with bovine, canine, human, and rat CL-P1, respectively. The CRD shares 23‑27% aa sequence identity with the CRD of collectins CL-L1, collectin sub-family member 11, MBL, SP-A1, and SP-D. Notably, this CRD recognizes galactose and fucose within the context of asialo-orosomucoids associated with the Lewisx epitope (8, 9). CL‑P1 is expressed in vascular endothelial cells and may play a role in bacterial recognition or as a scavenger receptor for desialylated glycoproteins (6, 8).
