Physical Appearance and Stability: Lyophilized Interleukin-16 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IL16 should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity: IL-16 was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4. Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized Interleukin-16 in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: Fully biologically active when compared to standard. Determined by its ability to chemoattract human CD4+ T-Lymphocytes using a concentration range of 50.0-100.0 ng/ml.
