The sequence of the first five N-terminal amino acids was determined and was found to be Met-Pro-Asp-Leu-Asn.
The ED50 as determined by its ability to chemoattract human CD4+ T lymphocytes using a concentration range of 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
IL-16 was lyophilized at 1 mg/ml in 10mM NaP, pH-7.5.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 90.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis SDS-PAGE.
It is recommended to reconstitute the lyophilized Interleukin-16 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Interleukin-16 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IL16 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 avoid multiple freeze-thaw cycles.
