The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Lys-Ser-Met-Gln.
The Biological activity is calculated by its ability to chemoattract human T cells at 10-100ng/ml corresponding to a Specific Activity of 1,000-10,000IU/mg.
The CCL1 protein was lyophilized with no additives.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 99.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized I-309 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized I-309 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution CCL1 should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
