Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.

Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.

Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.

Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.

Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.

Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4.
