LD78β is a CC chemokine that is closely related to MIP-1α. It signals through the CCR5 receptor and the β-chemokine receptor, D6. LD78β has been shown to exhibit potent activity in HIV suppression assays. Recombinant Human LD78β is a 7.7 kDa protein containing 70 amino acid residues, including the four conserved cysteine residues present in CC chemokines.
Amino Acid Sequence
Determined by its ability to chemoattract human monocytes using a concentration range of 1.0–10.0 ng/ml.
Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.
