Human Cytokine/Growth Factor/Chemokines Sample Spec sheets (subject to change without notice):


DATA SHEET:  recombinant HUMAN BRAK

Human BRAK is a newly discovered CXC chemokine, BRAK shares 30% identity with MIP-2 alpha and beta and shares several biological activities. This human BRAK is an 9.4kDa protein containing 77 amino acid residues.

Catalog#: RDI-3050

Package Size: 20 micrograms $231.00     $219.00/pack 2+

                    Mini-pack:cat#RDI-3050p $94.00/5ug

Supplied: sterile filtered,lyophilized protein with no additives

Source: E. Coli

Purity: >98% by SDS-Page analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug).

Reconstitution: The lyophilized protein soluble in water and most aqueous buffers. The lyophilized powder should first be quick spun in vial, then reconstituted in water to a concentration of 0.1-1.0mg/ml. Allow to set at least 30 minutes at 4 DEG C. If desired, can centrifuge for 1 minute at 1000 rpm to concentrate material in vial. This solution can be diluted into water or other buffered solutions or stored at 4 DEG C for up to 1 week or at -20 DEG C for future use.

Note:If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >10ug/ml.

Storage: The lyophilized powder, though stable at room temperature for a few weeks, is best stored dessicated at -20 DEG C. Reconstituted BRAK should be stored in working aliquots at -20 DEG C. Avoid Frequent Freeze-THAW Cycles.

Biological Activity: determined by its ability to chemoattract activated monocytes using a concentration range of 1.0-10.0ng/ml.
