APPLICATION

Application Note

Macrophage inflammatory protein-1β (MIP-1β), also known as CCL4 is a CC chemokine with specificity for CCR5 receptors. It is a chemoattractant for natural killer cells, monocytes and a variety of other immune cells. MIP-1β is a kind of chemotactic cytokine. Thus, chemotaxis assay used 24-well microchemotaxis system was undertaken to detect the chemotactic effect of MIP-1β on the human T-lymphocyte leukemia cell line Jurkat. Briefly, Jurkat cells were seeded into the upper chambers (100 μl cell suspension, 5x10⁵ cell/ml in RPMI-1640 with FBS free) and recombinant human MIP-1β (0. 0001 ng/ml, 0. 001 ng/ml, 0. 1 ng/ml, 1 ng/ml, 10 ng/ml, 100 ng/ml diluted separately in serum free RPMI-1640) was added in lower chamber with a polycarbonate filter (8μm pore size) used to separate the two compartments. After incubation at 37ºC with 5% CO₂ for 2h, the filter was removed, then cells in low chamber were observed by inverted microscope at low magnification (×100) and the number of migrated cells were counted at high magnification (×200) randomly. The recombinant human MIP-1β is able to induce migration of Jurkat cells.

Background

The protein encoded by this gene is a mitogen-inducible monokine and is one of the major HIV-suppressive factors produced by CD8+ T-cells. The encoded protein is secreted and has chemokinetic and inflammatory functions. [provided by RefSeq, Dec 2012]

The chemotactic effect of GTX00279-pro Human MIP1 beta protein (active).
Upper: (A) Jurkat cells were seeded into the upper chambers and serum free RPMI-1640 without MIP-1 beta was added in lower chamber, then cells in lower chamber were observed at low magnification (×100) after incubation for 2hrs.
(B) Jurkat cells were seeded into the upper chambers and serum free RPMI-1640 with 0.01 ng/ml MIP-1 beta was added in lower chamber, then cells in lower chamber were observed at low magnification (×100) after incubation for 2hrs.
Lower: The number of migrated cells were counted at high magnification (×200) randomly (five fields for each filter).
