Transfer Buffers

• Higher transfer efficiency than conventional products
• Simply change the transfer buffer
• No methanol needed

Method

After 60 minutes of (semi-dry) transfer at 25 V constant voltage, an appropriate exposure time for comparison of luminescence intensity was selected, and the luminescence intensity value of each protein was read and expressed as a relative value. After 60 minutes of (semi-dry) transfer at 25 V constant voltage, an appropriate exposure time for comparison of luminescence intensity was selected, and the luminescence intensity value of each protein was read and expressed as a relative value.
After the signals from low molecular weight proteins were read, the PVDF membrane was excised to measure the luminescence intensity of high molecular weight proteins, which require prolonged exposure, separately.

Results

Under constant voltage conditions, AquaBlot™ 10 x High Efficiency Transfer Buffer exhibited higher transfer efficiency than Towbin and Towbin (SDS) Buffers, in both the high and low molecular weight regions.

Method

After 60 minutes of (semi-dry) transfer at a constant current of 1.2 mA/cm2, an appropriate exposure time for comparison of luminescence intensity was selected, and the luminescence intensity value of each protein was read and expressed as a relative value. After the signals from low molecular weight proteins were read, the PVDF membrane was excised to measure the luminescence intensity of high molecular weight proteins, which require prolonged exposure, separately.
