LAG-1 is CC chemokine that signals through the CCR5 receptor. LAG-1 is identical to MIP-1beta (ACT II isotype) except for two amino acid substitutions; arginine for histidine at position 22 and serine for glycine at position 47 of the mature protein. LAG-1 chemoattracts monocytes, and exhibits activity as an HIV suppressive factor. Recombinant human LAG-1 is a 7.7 kDa protein containing 69 amino acid residues.
The lyophilized LAG-1 recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted LAG-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing LAG-1 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
