Human MDC Protein

• Catalog Number: orb429442
• Category: Tools
• Description: Recombinant of human CCL22 protein
• Form/Appearance: Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Solubility (25°C): It is recommended to reconstitute the lyophilized CCL22 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
• Protein Sequence: GPYGANMEDS VCCRDYVRYR LPLRVVKHFY WTSDSCPRPG VVLLTFRDKE ICADPRVPWV KMILNKLSQ
• Source: Escherichia Coli
• Biological Activity: Determined by its ability to chemoattract human T cells using a concentration range of 10ng-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
• Storage: Stability: Lyophilized CCL22 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL22 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles
• Buffer/Preservatives: CCL22 filtered (0.4µm) and lyophilized from a concentrated solution containing 20mM phosphate buffer & 500mM NaCl pH-7.4.
• Alternative names: C-C motif chemokine 22, Small-inducible cytokine A
• Note: For research use only
