Wet Tank Transfer Systems

Wet transfer is the most common and traditional strategy for western blot transfer due to its efficiency and throughput. We offer three systems for tank transfer that minimize the amount of transfer buffer required.

Convenient, reliable western transfer

Two Mini Blot Modules fit into the Mini Gel Tank and are designed to make your western transfers simple and easy to perform.

  • Universal module design—allows modules to fit in either chamber of the tank, simplifying the transfer setup
  • Unique gasket seal—helps prevent buffer leakage so there is no mess during setup of your western transfer
  • 1/2 inch buffer chamber—requires half the typical volume of methanol-based transfer buffers
  • Standard 60 min transfer protocol—accelerates your western workflow so you can get results faster
  • Robust electrodes, sturdy steel plates—for highly efficient and reliable western transfers

          Convenient, reliable wet transfer of midi gels

          Invitrogen SureLock Tandem Midi Gel Tank with Midi Blot Module

          When your western blotting workflow requires higher throughput, Invitrogen midi gels will allow you to load up to 26 samples per gel. You can use the SureLock Tandem Midi Gel Tank to run up to 2 high-performance Invitrogen midi gels and transfer them to membranes in the same tank using the SureLock Tandem Midi Blot Module. Two SureLock Tandem Midi Blot Modules fit into the innovative, dual-purpose SureLock Tandem Midi Gel Tank and are designed for easy, room-temperature gel transfers. Only 300 mL of methanol-containing buffer is required per gel transfer, reducing buffer and hazardous disposal costs.

          • 2-in-1 SureLock Tandem Midi Gel Tank—no need to purchase a separate tank for western transfers
          • Room temperature transfer—save the time, planning, and mess required with other systems to pre-chill buffers, freeze ice packs, or prepare ice baths
          • 300 mL per gel transfer buffer volume—lower transfer buffer volume requirement reduces reagent consumption and hazardous disposal costs
          • Fast and efficient—30-minute transfer without compromising performance
          • Easy to use—convenient blot assembly instructions are printed on the accessory transfer tray
          • Robust electrode plates—for highly efficient and reliable western transfers

          Consistent, reliable western blotting results

          When used with high-performance Invitrogen precast midi gels, you can depend on the SureLock Tandem Midi Gel Tank and Midi Blot Module to generate consistent, high-throughput western blots. The Invitrogen midi gels offer reproducible high-performance protein separation, resulting in sharp, well-resolved bands in straight lanes, and the SureLock Tandem Midi Blot Module provides dependable uniform transfer of proteins across the gel.

          To demonstrate the SureLock Tandem Midi Blot Module’s uniformity of transfer across a membrane, a NuPAGE 4-12% Bis-Tris Midi gel was loaded with recurring dilutions of E. coli lysate ranging from 2-0.25 µg and SeeBlue Plus2 Pre-stained Protein Standard. Electrophoresis was performed and the gel was transferred onto a 0.45 µm PVDF membrane. Results are shown in Figure 1.

          Densitometric Signal Linearity versus Protein Load

          Figure 1. Uniform transfer using SureLock Tandem Midi Gel Tank. Total protein normalization of transferred proteins shows uniform transfer across the blot. 

          A. No-Stain Reagent Labeled PVDF Blot. A NuPAGE 4-12% Bis-Tris Midi gel was loaded with recurring dilutions of E. coli Lysate ranging from 2 to 0.25 µg and SeeBlue Plus2 Pre-stained Protein Standard in lanes 1-2 and 19-20. The gel was electrophoresed using MES running buffer in the SureLock Tandem Midi Gel Tank. Proteins from the gel were transferred onto a 0.45 µm PVDF membranes at 25V constant for 30 minutes using the SureLock Tandem Midi Blot Module. After transfer, the proteins on the membrane were labeled following the No-Stain Protein Labeling Reagent protocol for midi-sized membranes. The image was captured using an iBright Imager with the No-Stain Membrane epi setting (455-485 nm excitation and 565-615 nm emission). As the SeeBlue Plus2 Pre-stained Protein Standard is already labeled, its protein bands are not all susceptible to labeling with No-Stain Reagent, and therefore are not all visible in this image. 

          B. Densitometric Signal Linearity versus Protein Load. The densitometric signal intensity was determined for each lane. Technical replicates (n=4) were averaged and plotted to determine the linear regression for the entire concentration range (R2=0.9994). Error bars represent standard deviation.

Proteins from the gel were transferred onto a 0.45 µm PVDF membranes at 25V constant for 30 minutes using the SureLock Tandem Midi Blot Module. After transfer, the proteins on the membrane were labeled following the No-Stain Protein Labeling Reagent protocol for midi-sized membranes. The image was captured using an iBright Imager with the No-Stain Membrane epi setting (455-485 nm excitation and 565-615 nm emission). As the SeeBlue Plus2 Pre-stained Protein Standard is already labeled, its protein bands are not all susceptible to labeling with No-Stain Reagent, and therefore are not all visible in this image. 

                  B. Densitometric Signal Linearity versus Protein Load. The densitometric signal intensity was determined for each lane. Technical replicates (n=4) were averaged and plotted to determine the linear regression for the entire concentration range (R2=0.9994). Error bars represent standard deviation.
