OneMinute
Western Blot Stripping Buffer
In
ONE minute, your membrane is ready for reprobing |
|
|
For saving time and precious samples, researchers often strip off the first set of primary and secondary antibodies after performing Western Blot detection in order to detect different proteins on the same membrane. However, they usually suffer either significant loss of target proteins from stripping the blot using harsh stripping buffer, or incomplete removal of the antibodies from using mild stripping
buffer. OneMinute Western Blot Stripping Buffer was developed to help you effectively strip off high-affinity antibodies without removal of transferred proteins on the membrane.
OneMinute Western Blot Stripping Buffer, a revolutionary stripping buffer, immediately makes your membrane ready for multiple re-probes in
ONE minute. It provides a faster and easier way to strip off high-affinity primary and secondary antibodies on the membrane. It reduces incubation times while stripping at room temperature, and re-blocking the blots usually is not necessary.
It spends only 30 seconds for stripping and 3x 10 seconds for washing.
OneMinute Western Blot Stripping Buffer is harsh for antibodies, but gentle to transferred proteins on the membrane. It effectively strips off primary and secondary antibodies without removal of transferred proteins, which allows the use of a single membrane for up to 10 times re-probes. In contrast, traditional stripping condition is so harsh that loss of transferred proteins is inevitable and the blots can hardly be re-probed for more than 2~3 times.
OneMinute Western Blot Stripping Buffer
is effective with both nitrocellulose and PVDF membranes, and various antibody conjugates (HRP, AP, etc.).
It is conveniently stored at room temperature and used without dilution.

Protocols:
|
|
1.
Immerse membrane in OneMinute Western Blot Stripping Buffer
for 30 sec.

Re-probing with different antibodies. 5% milk
blocked nitrocellulose Western blots of 293 cell lysate
were probed with Rabbit-anti-Human JNK1 (Protein1, Santa
Cruz, sc-747) at 1:200 dilution, HRP-Goat-anti-Rabbit
(Amersham) at 1:10,000 dilution. The signal was detected
using ECL substrate (Panel A). Blots were stripped with
either 2ml of OneMinute Stripping Buffer (30
sec, RT) or 10ml of competitor stripping buffer
(15min, 50℃) (Panel B). OneMinute
Buffer treated blot was washed 3x 10sec with TBST, and
performed re-probing directly without re-blocking.
Competitor stripping buffer treated blot was washed 3x
10min, blocked by 5% milk for 1 hour, and washed 3x 15min
with TBST. Blots were re-probed with Mouse-anti-Human
RIPK1 (Protein2, BD, 610458) at 1:200 dilution, HRP-Goat-anti-Mouse (Amersham) at
1:2,000 dilution and detected with ECL substrate (Panel

2ml of OneMinute Stripping Buffer (30sec,
RT),
or 10ml of competitor stripping buffer (P's R product) for
either 30 sec or 15min at RT (Panel B). OneMinute
Buffer treated blot was washed 3x 10 sec with TBST, and
directly re-probed without re-blocking. Competitor stripping buffer treated blot was washed 3x 10min, blocked with 5% milk for 1hour, and washed 3x 15min with TBST. Blots were re-probed with
Mouse-anti-Human IKKgamma (protein
2, BD, 559675) at 1:200 dilution,
HRP-Goat-anti-Mouse (Amersham) at 1:2,000 dilution and detected with ECL substrate (Panel
C). The removal of the primary
antibody against Protein 1 was also evaluated by using
same secondary antibodies (Anti-Mouse). 15min stripping
with competitor P's R product completely removed
secondary antibody (right lane in Panel B) but failed to
completely remove primary antibody (right lane in Panel
C). |
