About this item

Functional biotin labeled human CCL4 chemokine with very low endotoxin levels.

Extremely low endotoxin levels (<0.01 EU per 1 μg) Functional activity tested and validated For use in various streptavidin applications: Flow cytometry, microscopy, and other imaging techniques

Monokine with inflammatory and chemokinetic properties. Binds to CCR5. One of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant MIP-1-beta induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). The processed form MIP-1-beta(3-69) retains the abilities to induce down-modulation of surface expression of the chemokine receptor CCR5 and to inhibit the CCR5-mediated entry of HIV-1 in T-cells. MIP-1-beta(3-69) is also a ligand for CCR1 and CCR2 isoform B.
