产品描述 概述Human CCL13 is belonging to the CC chemokine family and is encoded by the gene CCL13 in humans. CCL13 (MCP-4) shares 56-61 % sequence identity with MCP-1 (CCL2) and MCP-3 (CCL7) and is 60 % identical to Eotaxin (CCL11). CCL13 was a potent chemoattractant for monocytes and eosinophils and stimulated histamine release from basophils. CCL13 can induce a calcium flux in HEK-293 cells transfected with the receptor CCR2B and CCR3. That shows the function receptors of CCL3 are CCR2B and CCR3. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Purity | > 96 % by SDS-PAGE and HPLC analyses. | Source | Escherichia coli. | Biological Activity | Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human monocytes is in a concentration of 10-100 ng/ml. | Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 130 mM NaCl. | Endotoxin | Less than 1 EU/μg of rHuMCP-4/CCL13 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. | AA Sequence | QPDALNVPST CCFTFSSKKI SLQRLKSYVI TTSRCPQKAV IFRTKLGKEI CADPKEKWVQ NYMKHLGRKA HTLKT |
