Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Description

This recombinant human CCL13 protein is expressed in E. coli and contains an amino acid sequence corresponding to the region 24-98aa of the human CCL13 protein. The product is tag-free and provided as a lyophilized powder, which can be reconstituted in sterile water or buffer before use. The purity of the protein is >96%, as determined by SDS-PAGE and HPLC, and the endotoxin level is less than 1.0 EU/µg, as measured by the LAL method. The recombinant CCL13 is fully biologically active when compared to the standard, and its activity has been determined by a chemotaxis bioassay using human monocytes at a concentration of 10-100 ng/ml.

C-C motif chemokine 13 (CCL13) is a small secreted protein belonging to the CC chemokine family. It is involved in the recruitment and activation of immune cells, particularly monocytes, and plays a crucial role in immune and inflammatory responses. Research in the area of immunology has been focused on understanding the function and regulation of CCL13 and its role in various immune-mediated diseases.

Target Background

Function

Chemotactic factor that attracts monocytes, lymphocytes, basophils and eosinophils, but not neutrophils. Signals through CCR2B and CCR3 receptors. Plays a role in the accumulation of leukocytes at both sides of allergic and non-allergic inflammation. May be involved in the recruitment of monocytes into the arterial wall during the disease process of atherosclerosis. May play a role in the monocyte attraction in tissues chronically exposed to exogenous pathogens.
