Storage, Stability and Shipping:

The lyophilized protein is stable for at least one year from date of receipt at -70^oC. Upon reconstitution, this cytokine can be stored in working aliquots at 2^o - 8^oC for one month, or at -20^oC for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Endotoxin Level:

<1.0 EU/μg of recombinant protein as determined by the LAL method.

Molecular Weight:

10.4 kDa

Reconstitution Protocol:

Reconstitute in sterile PBS at 25µg/mL (containing at least 0.1% human or bovine serum albumin).

Sample Cell Assay Data:

The ED50 is 2.5-12 ng/mL as determined by its ability to chemoattract activated lymphocytes (at a concentration of 100.0 ng/mL).

Purity:

Recombinant Human CXCL16 resolved on a 17% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250.
