Specifications

LD78-beta is a 7.8kD protein containing 70 amino acid residues, which is closely related to MIP-1-alpha. LD78-beta has enhanced receptor binding affinities to CCR5 and the beta-chemokine receptor, D6 and has also been shown to exhibit activities in HIV-suppression assays.
Catalog #	L1585
Source	E.coli
Form	Sterile-filtered solution was lyophilized without additives
Stability	The lyophilized protein, though stable at room temperature, is best stored desiccated below 0°C. Reconstituted LD78-beta should be stored in working aliquots at -20°C.
Purity	98% by SDS-PAGE and HPLC analyses.
Endotoxin	0.1ng/ug (1EU/ug)
Reconstitution	We recommend a quick spin followed by reconstitution in water to a concentration of 0.1-1mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or at -20°C for future use.
Biological Activity	Determined by its ability to chemoattract human monocytes using a concentration range of 1-10ng/ml.
