Description: Human recombinant LAG-1 produced in E.coli is a single, non-glycosylated polypeptide chain containing 94 amino acids (24-92) and having a molecular mass of 10.5kDa (Molecular weight on SDS-PAGE will appear higher). CCL4L1 (C-C motif chemokine 4-like) is a member of to intercrine beta (chemokine CC) family. The CCL4L1 protein is similar to CCL4 which inhibits HIV replication in peripheral blood monocytes which express CCR5.
