Immunofluorescence
Immunofluorescence Staining of Human Cells by Lysed Whole Blood Method
- Add 100 µl of well-mixed anticoagulated whole blood to the bottom of a labeled tube. (We use EDTA as the anticoagulant.)
- Add the appropriate primary antibody to each tube. If using unlabeled antibody, a titration is suggested. Conjugated antibody should be used as directed, usually 5 or 20 µl per sample for the pre-diluted test size products from BD Biosciences. Since applications vary, each investigator should titrate reagents to obtain optimal results.
- Mix well, then incubate in the dark at room temperature for 20-30 minutes.
- Remove tubes from dark chamber and mix each tube well. Add 2 ml of lysing solution to each tube. Vortex each tube.
- Incubate at room temperature in the dark for 10-15 minutes.
- Centrifuge for 5 minutes at 1000 rpm (200 x g).
- Remove supernatant by aspiration. Then vortex and add 2 ml washing solution to each tube.
- Centrifuge for 5 minutes at 1000 rpm (200 x g).
- Remove supernatant by aspiration.
- If required, add appropriate second step antibody (at optimal concentration) to each tube and vortex gently (if second step antibody is not required, proceed to step 18).
- Incubate in the dark at room temperature for 20-30 minutes.
- Remove from the dark.
- Mix well, then add 2 ml washing buffer to each tube.
- Centrifuge for 5 minutes at 1000 rpm (200 x g).
- Remove supernatant by aspiration and vortex.
- If a third step is not required, proceed to step 18. For third step, add an appropriate third-step reagent (at optimal concentration) to each tube and vortex gently.
- Repeat steps 11-15.
- If you will analyze the same day, add 500 µl wash buffer to each tube, vortex, and analyze within 8 hours. If not, fix cells by resuspending in 2% paraformaldehyde buffer* (30 minutes, room temperature), and wash with wash buffer. Resuspend cells in 500 µl wash buffer and store in the refrigerator at 2-8°C for up to 36 hours.
*Extended storage of fluorescent dyes in paraformaldehyde may affect fluorescence. We recommend using our BD Stabilizing Fixative (cat. no. 338036) for preserving immunofluorescent staining (see the TDS for detailed instructions).
