Western Blot Stripping Buffer
The Western BLoT Stripping Buffer is an answer for eradicating main and secondary antibodies from probed Western blot membranes. Antibody removing with this buffer can happen below delicate circumstances (room temperature, 30 min incubation), minimizing lack of immobilized protein from the membrane. When utilizing a PVDF membrane, the identical membrane could be stripped and reprobed 2–5 occasions. After stripping, membranes could be re-probed, both with a unique focus of main antibody or with a wholly completely different main antibody.

| The Western BLoT Stripping Buffer is a reagent that may take away main and secondary antibodies from Western blot membranes. After therapy with the Stripping Buffer, the membrane could be reused; it’s attainable to probe the membrane with both a unique focus of main antibody or with a wholly completely different main antibody. With this product, the antibody removing response proceeds below comparatively delicate circumstances (room temperature, 30 minutes), and due to this fact there may be little or no lack of immobilized protein from the membrane. When utilizing a PVDF membrane, the identical membrane could be stripped and re-probed 2–5 occasions. | ||||||

Stripping and re-probing of Western blots presents a number of benefits:
- Conservation of samples which can be costly or accessible solely in restricted portions;
- Analysis of a given blot utilizing a number of completely different antibodies, e.g. subtype- or isoform-specific antibodies;
- Re-analysis of anomalous outcomes and affirmation with the identical or a unique antibody;
- Correcting errors in incubation with the fallacious antibody;
- Cost financial savings in reagents and time by reusing the identical blot.
Several protocols for antibody stripping from Western blots have been printed, together with these which make the most of low pH, warmth and detergent, and chaotropic brokers. Three advisable protocols are offered under. The first is relevant to any chemiluminescent substrate system and makes use of a mix of detergent and warmth to launch the antibodies. The second is usually used for purposes the place antibodies should be separated from an antigen and employs low pH to change the construction of the antibody in such a means that the binding website is not energetic.
The third protocol employs the ReBlot™ Plus Western Blot Recycling Kit which has been particularly formulated for stripping antibodies from Western blot membranes. Benefits of this strategy embody
- Avoidance of odor associated to β-mercaptoethanol.
- Room temperature processing.
- Removal of antibodies in 15 minutes.
None of those strategies will take away the coloured precipitates generated from chromogenic detection methods (e.g., BCIP, 4CN, DAB and TMB). However, it’s nonetheless attainable to research the blot with one other antibody particular to a unique goal protein.
Usually, these protocols ought to solely be used for qualitative functions, except it has been established that stripping doesn’t quantitatively have an effect on a given antigen. Depending upon the tactic and sort of membrane used, many antigens will face up to not less than 5 stripping cycles. However, it’s to be considered that in every stripping cycle small parts of membrane-immobilized proteins might be eliminated. When a number of antigens are to be detected sequentially, it is strongly recommended to begin with antigens that are anticipated to happen at decrease abundance or yield much less sign.
Here are some further suggestions when planning a Western blot experiment with a number of rounds of antibody stripping.
- PVDF membranes are extra strong than nitrocellulose and are due to this fact advisable for any protocol involving antibody stripping.
- Drying of PVDF membranes instantly after switch from the SDS-PAGE gel improves binding of proteins to the membrane and is especially advisable when a number of stripping is deliberate. Dry PVDF membranes should be rewetted with alcohol previous to the primary spherical of immunodetection.
- Detect low-abundance antigens first.
- Use low-affinity antibodies earlier than high-affinity antibodies.
- Important: Although drying of a PVDF blot is advisable instantly after switch, the blot shouldn’t be allowed to dry between rounds of immunodetection. Any residual antibody molecules will bind completely to the membrane whether it is allowed to dry.
