Detergent-based Western Blot Stripping Buffer

Stripping and re-probing a Western blot enables sample conservation and fast correction or adjustments of antibody concentration and incubation time. This recipe is for a Western blot stripping solution that uses the surfactant sodium dodecyl sulfate (SDS) and the reducing agent β-mercaptoethanol (BME) to remove antibodies and chemiluminescent or fluorescent detection reagents.

This calculator enables the accurate preparation of this detergent-based Western blot stripping solution for any milliliter volume. Input your desired volume, click the CALCULATE button, and the table will populate with the amounts of each component needed.

100 mL Recipe Desired Volume: mL
20 mL of 10% SDS (71736) mL of 10% SDS
12.5 mL of 0.5 M Tris-HCl pH 6.8 (FW 157.60) mL of 0.5 M Tris HCl pH 6.8
0.8 mL of β-mercaptoethanol (63689) mL of β-mercaptoethanol

Procedure
  1. In a fume hood, place the blot in detergent stripping buffer and incubate with agitation for 30 minutes at 50 °C.
  2. Place the blot in 1X PBS and agitate for 10 minutes. Repeat with fresh buffer.
  3. Optional: Repeat the initial detection protocol (omitting the primary antibody step) to make sure that the antibodies have been inactivated or removed from the membrane.
  4. Place the blot in fresh 1X PBS and agitate for 10 minutes.
  5. Proceed to the blocking step for the next round of immunodetection.
