Recombinant Mouse CLEC-2/CLEC1B Protein, CF Summary

Product Specifications

Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its binding ability in a functional ELISA. When Recombinant Mouse Podoplanin Fc Chimera (Catalog # 3244-PL) is coated at 1.0 µg/mL (100 μL/well), Recombinant Mouse CLEC‑2/CLEC1B binds with a typical ED50 of 0.1-0.5 μg/mL.

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: CLEC-2/CLEC1B

C-type lectin-like receptor 2, also known as CLEC-1B, is a 32 kDa type II transmembrane glycoprotein that is expressed on platelets, megakaryocyte, and liver sinusoidal cells (1-4). Mature mouse CLEC-2 consists of a 31 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 177 aa extracellular domain (ECD) with one C-type lectin domain. Within the ECD, mouse CLEC-2 shares 59% and 90% aa sequence identity with human and rat CLEC-2, respectively. Alternative splicing generates a short isoform that lacks the transmembrane segment. CLEC-2 binding to Podoplanin trigger platelet activation, shedding of GPVI, and cleavage of Fcg RIIA/CD32a (5-8). CLEC-2 expression on platelets is required for the development of lymphatic vessels and valves as well as the maintenance of lymph node high endothelial veinules (HEV) during lymphocyte crossing (7-10). CLEC-2 additionally binds to fucoidan, HIV-1, and the platelet-aggregating snake venom protein Rhodocytin/Aggretin (2, 3, 11). In the liver, soluble CLEC-2 promotes M2 macrophage differentiation and limits inflammatory cytokine production (12).
