SureCast Gel Handcast System assembly
Step 1: Set-up
Set the handcast station on a level surface.
Step 2: Assemble
Assemble the glass plates with the silicone spacer between them so that all the outer edges are flush.
Step 3: Secure
Place the glass plate assembly in the handcast station. Hold the glass plate assembly to prevent shifting, and close the handle to secure the glass plates in the handcast station.
Step 4: Pour
Tilt the handcast station to recline on the heel. Add resolving gel solution to the glass plates until the solution reaches the level of the fill line.
Allow the resolving gel to polymerize (5–10 min). Verify polymerization.
Tilt the handcast station to recline on the heel. Add the stacking gel solution until it reaches the upper edge of the front glass plate. Set the handcast station back to the upright position.
Step 5: Finish
Insert the comb slowly by starting at one end and sliding it between the glass plates until both ends are in place. Allow the stacking gel to polymerize (5–10 min). Verify polymerization.
Then, release the clamp and remove plate. The gel is ready for use.
Gel casting recipes with SureCast reagents
Choose the polyacrylamide percentage for your application based upon the expected molecular weight of your protein of interest and the volume of your sample. Resolve large molecules with low percentage gels and small molecules with high percentage gels. If the molecular weight of the molecule is unknown, or the sample contains a wide range of molecules, use a mid-range percentage gel.
Prepare resolving gel solution according to the volumes in the following table. The volumes provided in the table are for a single gel. Scale volumes proportionally based on the number of gels to be cast.
Note: Solutions do not require degassing.
| Polyacrylamide % | |||||||||

Customer story
"We have used the SureCast system for one semester and I love them! The system is easy to use; the students can have the system set up in no time without any assistance from the TAs or myself and it does not leak. With the (other supplier’s) system, the TAs and I would be running around the lab trying to stop leaking gels, or showing students how to set up the apparatus properly, even after giving a demo to the class. This past semester, the TAs and I sat down and watched the students work! The gels themselves are bigger and thicker - just because I used to use 0.75mm spacers and the ones provided with the SureCast system are 1mm spacers- so I do go through more acrylamide, but not significantly more because of all the leaking with the old system.
As far as the tanks go, I love them as well. Advantages are that the gels are side by side, so it is easier for students to load and therefore speeds up the lab. Additionally, no blank plate is required for a dam if there are an odd number of gels being used. That simplifies things for the students as well.
Honestly, I am so happy we converted and regret it wasn't done sooner."
