Description：Mouse monoclonal antibody FITC labled to CD19Immunogen：Native purified human CD19.Purification：The antibody was purified by affinity chromatography.Clonality：Monoclonal (clone: CB19)Conjugation：FITCForm：Mouse IgG1. Liquid in PBS, pH 7.3, 0.2% BSA, and 0.02% sodium azide.Dilution：10 μl / assayGene Symbol：CD19Alternative Names：B-lymphocyte antigen CD19; B-lymphocyte surface antigen B4; Differentiation antigen CD19; T-cell surface antigen Leu-12; CD antigen CD19 Entrez Gene (Human)： 930; SwissProt (Human)： P15391; Directions for Use：1. Take 100 μl peripheral blood anticoagulated by EDTA and add to the bottom of 5 ml tube. 2. Add 10 μl labeled antibody to the bottom of flow tube mixing with the whole blood, incubate for 20 minutes at room temperature away from light. 3. Add 2 ml RBC lysis buffer, incubate for 10 minutes away from light after mixing, dissolve red blood cells. 4. Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant. 5. Add 2 ml PBS wash buffer to resuspend the cells, then 1000 rpm centrifugation for 5 minutes, discard the supernatant. 6. Add 0.5 ml PBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 °C then measured).Storage/Stability：Shipped and store at 4°C for one year. Do not freeze.
