General description
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.

Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. 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.
