- Description
- Description: This D8SEE monoclonal antibody reacts with human CD194 (CCR4). CD194, also known as C-C Chemokine Receptor 4 (CCR4) is a member of the G protein-coupled receptor family, a large family characterized by seven transmembrane alpha helical domains. The ligands for CCR4 are CCL17 (TARC) and CCL22 (MDC), which direct the migration of target cells. CCR4 and its ligands, along with the other receptors CCR10 and CLA, are particularly important for the recruitment of T cells into the skin, where they may also play a role in adhesion and extravasation. Although CCR4 expression was originally believed to be restricted to Th2 cells, it has since been observed in some subsets of Th17, Treg, and Th1 cells. It is not expressed by naive T cells, indicating a role in memory or effector function. Other cells that express CCR4 are activated NK cells, platelets, monocytes, and basophils. Applications Reported: This D8SEE antibody has been reported for use in flow cytometric analysis. Applications Tested: This D8SEE antibody has been pre-titrated and tested by flow cytometric anaylis of normal human peripheral blood cells. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Figure 3. Expression levels of chemokine receptors on CIK cells generated from patients with CRC and healthy donors. (A) Analysis of the expression levels of CCR4, CCR5, CCR7, CXCR3 and CXCR4 on CIK cells via flow cytometry revealed that CXCR3 and CXCR4 had higher expression levels on CIK cells compared with isotype, expression profiles of CCR4, CCR5 and CCR7 did not show significant changes compared with isotype. (B) Dynamic changes of chemokine receptors CCR4, CCR5, CCR7, CXCR3 and CXCR4 of CIK cells on D7, 14, 21 and 28 were detected in patients with CRC and HD CIK cells via flow cytometry. The result revealed that expression levels of CXCR3 and CXCR4 were significantly higher on CIK cells cultured from CRC compared with HD at all the time points analyzed, while the expression levels of CCR4, CCR5 and CCR7 were significantly higher on CIK cells cultured from CRC compared with HD at different time points analyzed (CCR4 on D7 and D28; CCR5 on D28; CCR7 on D7, D21 and D28). All comparisons were performed using unpaired Student''s t-test with Welch''s correction. *P
