Recombinant Murine Macrophage Inflammatory Protein-3 beta/CCL19 (rMuMIP-3b/CCL19)
Catalogue Numbers: PR2029-5, PR2029-20
Sizes: 5µg, 20µg
Source: Escherichia coli
Molecular Weight: Approximately 9.2 kDa, a single non-glycosylated polypeptide chain containing 83 amino acids.
Purity: >95% by SDS-PAGE and HPLC analyses.
Biological Activity: Measured by its ability to chemoattract human CCR7 transfected BaF3 mouse proB cells.
The ED50 for this effect is typically 3-15 ng/mL.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
AA Sequence: GANDAEDCCL SVTQRPIPGN IVKAFRYLLN EDGCRVPAVV FTTLRGYQLC APPDQPWVDR IIRRLKKSSA KNKGNSTRRS PVS
Endotoxin: Less than 1EU/μg of rMuMIP-3b/CCL19 as determined by LAL method.
Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
Storage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Usage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China
Description: Macrophage Inflammatory Protein-3 beta also called CCL19, ELC (EBI1 Ligand Chemokine), Exodus-3 is a reported β chemokine that binds specifically to the chemokine receptor CCR7 / EBI1 / BLR2. It is expressed in the thymus, lymph nodes and in activated bone marrow stromal cells. MIP-3 beta is a chemoattractant for T and B lymphocytes and myeloid progenitor cells.
