Immunofluorescence (Immunocytochemistry)

A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

  1. 20X Phosphate Buffered Saline (PBS): (9808) To prepare 1L 1X PBS: add 50 ml 20X PBS to 950 ml dH2O, mix. Adjust pH to 8.0.
  2. Formaldehyde: 16%, methanol free, Polysciences, Inc. (cat# 18814), use fresh and store opened vials at 4°C in dark, dilute in 1X PBS for use.
  3. Blocking Buffer (1X PBS / 5% normal serum): To prepare 10 ml, add 0.5 ml 20X PBS, 1.25 ml normal serum from the same species as the secondary antibody (e.g., Normal Goat Serum (#5425)) and 9.0 mL dH2O and mix well.
  4. Antibody Dilution Buffer (1X PBS / 1% BSA): Add 0.1 g BSA (9998) to 10 ml 1X PBS and mix well.
  5. Recommended Fluorochrome-conjugated Anti-Mouse secondary antibodies:

    NOTE: When using any primary or fluorochrome-conjugated secondary antibody for the first time, titrate the antibody to determine which dilution allows for the strongest specific signal with the least background for your sample.

  6. Prolong® Gold AntiFade Reagent (#9071), Prolong® Gold AntiFade Reagent with DAPI (#8961).

B. Specimen Preparation - Cultured Cell Lines (IF-IC)

NOTE: Cells should be grown, treated, fixed and stained directly in multi-well plates, chamber slides or on coverslips.

  1. Aspirate liquid, then cover cells to a depth of 2–3 mm with 4% formaldehyde in 1X PBS.
    NOTE: Formaldehyde is toxic, use only in fume hood.
  2. Allow cells to fix for 15 minutes at room temperature.
  3. Aspirate fixative, rinse three times in 1X PBS for 5 minutes each.
  4. Proceed with Immunostaining (Section C).

C. Immunostaining

NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

  1. Block specimen in Blocking Buffer for 60 minutes.
  2. While blocking, prepare primary antibody by diluting as indicated on datasheet in Antibody Dilution Buffer.
  3. Aspirate blocking solution, apply diluted primary antibody.
  4. Incubate overnight at 4°C.
  5. Rinse three times in 1X PBS for 5 minutes each.
  6. Incubate specimen in fluorochrome-conjugated secondary antibody diluted in Antibody Dilution Buffer for 1–2 hours at room temperature in dark.
  7. Rinse in 1X PBS as in step 5.
  8. Coverslip slides with Prolong® Gold Antifade Reagent (#9071), Prolong® Gold AntiFade Reagent with DAPI (#8961).
  9. For best results, examine specimens immediately using appropriate excitation wavelength. For long-term storage, store slides flat at 4°C protected from light.

Flow Cytometry, Extracellular Epitope Protocol for Mouse Antibodies

A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 1X Phosphate Buffered Saline (PBS): To prepare 1 L 1X PBS: add 100 ml 10X PBS (#12528) to 900 ml water, mix.
  2. 4% Formaldehyde, Methanol-free (#47746), Optional
  3. Antibody Dilution Buffer: Purchase ready-to-use Flow Cytometry Antibody Dilution Buffer (#13616), or prepare a 0.5% BSA PBS buffer by dissolving 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.
  4. Recommended Anti-Mouse secondary antibodies:

NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com/flowdyes for a listing of cellular dyes validated for use in flow cytometry.

NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.

B. Fixation

NOTE: If live cell staining is desired, proceed to Section C.

  1. Pellet cells by centrifugation and remove supernatant.
  2. Resuspend cells in approximately 100 µl 4% formaldehyde per 1 million cells. Mix well to dissociate pellet and prevent cross-linking of individual cells.
  3. Fix for 15 min at room temperature (20-25°C).
  4. Wash by centrifugation with excess 1X PBS. Discard supernatant in appropriate waste container. Resuspend cells in 1X PBS.

C. Immunostaining

NOTE: Count cells using a hemocytometer or alternative method.

  1. Aliquot desired number of cells into tubes or wells. (Generally, 5x105 to 1x106 cells per assay.)
  2. Pellet cells by centrifugation and remove supernatant.
  3. Resuspend cells in 100 µl of diluted primary antibody, prepared in Antibody Dilution Buffer at the recommended dilution.
  4. Incubate for 30-60 minutes at room temperature (20-25°C).
  5. Wash by centrifugation in Antibody Dilution Buffer. Discard supernatant. Repeat.
  6. Resuspend cells in 100 µl of diluted fluorochrome-conjugated secondary antibody, prepared in Antibody Dilution Buffer at the recommended dilution.
  7. Incubate for 30 minutes at room temperature.
  8. Wash by centrifugation in incubation buffer. Discard supernatant. Repeat.
  9. Resuspend cells in 200-500 µl of 1X PBS and analyze on flow cytometer.

Protocol Id: 36

Specificity / Sensitivity

SSEA4 (MC813) Mouse mAb detects endogenous levels of SSEA4 antigen.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by injecting animals with human embryonal carcinoma 2102Ep cl.2A6 cells.

Background

SSEA4 (stage-specific embryonic antigen 4) is a glycolipid carbohydrate epitope expressed on the surface of human teratocarcinoma stem cells, human embryonic germ cells, and human embryonic stem cells (1). Expression of human SSEA4 decreases following differentiation of human embryonal carcinoma cells. Expression of the SSEA4 antigen is absent in murine pluripotent cells, but increases following differentiation (1,2).
