Induced chemotaxis of human PBMC cells assay for Human MIP-1 β. Cells that migrated were counted using a luminescent substrate. Migration over basal levels was reported in response to Human MIP-1 β starting at 3.1 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human MIP-1 β has a predicted Mw of 7.8 kDa.

Description

Macrophage Inflammatory Protein 1 β (MIP-1 β), also known as CCL4, is produced by macrophages and functions as a mitogen-inducible cytokine. MIP-1 β signals through the chemokine receptor CCR5 to chemoattract immune cells. MIP-1 β induces inflammatory responses, including neutrophil superoxide production. The MIP-1 α and MIP-1 β heterodimer exhibits antiviral activity against the human immunodeficiency virus 1 (HIV-1).

Activity Assay

Human MIP-1 β is fully biologically active when compared to standard. The activity is determined by the ability to induce chemotaxis of human PBMC cells.
