Exodus-2 has a unique 36 (murine) or 37 (human) amino acid carboxyl-terminal extension not seen in other chemokines. Exodus-2 selectively stimulates the chemotaxis of adult T-lymphocytes and is expressed preferentially in lymph node tissue. Exodus-2 is critical for adult T-cell adhesion to high endothelial venules in lymph nodes, a rate-limiting step for T cell trafficking through nodal tissue.
<1.0 EU/μg of recombinant protein as determined by the LAL method.
Biological Activity Comment
Determined by its ability to chemoattract total lymphocyte population using a concentration range of 10-100 ng/mL.
Weight
12.0 kDa
Description
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Format
Lyophilized PowderRecombinant mouse Exodus-2 was lyophilized from a 0.2 μm filtered PBS solution.
Purity
>95% as determined by SDS-PAGE
Storage
The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
