COMBI IC Reagent: IgG Negative Control (FITC) and IgG Negative Control (PE)

Permeabilization and Staining Procedure - In combination with our Permeabilization Kit FIX&PERM® (Cat. No. GAS-002) intracellular isotype controls can be easily stained in cell suspensions. - For each sample to be analyzed add 50 ul of whole blood, bone marrow or mononuclear cell suspension in a 5ml tube - Add 100 ul of Reagent A (Fixation Medium, stored and used at room temperature) - Incubate for 15 minutes at room temperature - Add 5 ml phosphate buffered saline and centrifuge cells for 5 minutes at 300 g - Remove supernatant and add to cell pellet 100 ul Reagent B (Permeabilization Medium) and 20 ul of COMBI-IC Negative Control antibody conjugate. - Vortex at low speed for 1-2 seconds - Incubate for 15 minutes at room temperature - Wash cells with phosphate buffered saline as described above - Remove supernatant and resuspend cells in sheath fluid for immediate analysis or resuspend cells in 0.5 ml 1.0 % formaldehyde and store them at 2-8°C in the dark. Analyze fixed cells within 24 hours.

This ready to use Negative Control reagent contains a combination of fluorescein and phycoerythrin conjugated mouse immunoglobulin molecules of IgG1 isotype, which have been selected on the basis of their binding characteristics: no specific binding to human intracellular or cell surface antigens, same low range of nonspecific binding to human leukocytes as other COMBI-IC-Reagents. Like all other COMBI-IC-reagents, this reagent should be used in combination with our FIX&PERM® Cell Permeabilization Kit (Cat.No. GAS-002) These isotype control IgG1 are suitable as negative controls to be used in combination with COMBI-IC reagents for the: - Enumeration of Myeloid Cells - Analysis of Myeloid Differentiation Stage - Enumeration of B-cells and Precursors - Enumeration of T-cells and Precursors - Analysis of Leukemia Cells - Analysis of Immunodeficiency States Results must be interpreted by a certified professional before final interpretation. Analyses performed with this antibody should be paralleled by positive and negative controls. If unexpected results are obtained which cannot be attributed to differences in laboratory procedures, please contact us.

For professional users only. This reagent contains sodium azide. To avoid the development of hazardous conditions reagents containing azide should be diluted in running water prior to be discarded. Similar to the work with other biological products proper handling procedures are recommended.
