SECTION 1 General Information 1.1 Introduction The C.B.S. Scientific Adjustable Nucleic Acid Sequencers features the flexibility of running path lengths from 22cm up to 1 meter. This adjustable feature allows for rapidly changing research priorities for the individual laboratory researcher.
1.3 Safety Power to the Sequencing unit is to be supplied by an external DC voltage power supply that must be ground isolated so that the DC voltage output floats with respect to ground. Current to the unit, provided from the external power supply, must enter the unit through the lid assembly, providing a safety interlock to the user. Current to the unit is broken when the lid is removed.
Section 2 Description of Parts 2.1 Unpacking- Adjustable Height Sequencer Please verify that your sequencing unit comes complete with the following components: • Buffer reservoirs, upper & lower with safety covers with attached power leads Drain plugs installed in upper reservoir • 6 white spring clamps (Cat.
2.2 Unpacking- Dual Adjustable Height Sequencer Please verify that your sequencing unit comes complete with the following components: • Buffer reservoirs, divided upper & lower with safety covers/power leads • Drain plugs installed in upper reservoir • Twelve white spring clamps (Cat.
Section 3 Assembly 3.1 Unit Assembly for Adjustable Height Sequencer 1. Place the Adjustable Sequencer on a level work surface in an authorized work area. Attach three guide rods to base. Tilt base on its side, place stainless steel screw through countersunk hole and screw the guide rods onto the base. 2. Secure lower reservoir to base by tightening the two black knurled thumb screws. 3.
3.3 Glass Plate Preparation 1. Select a pair of glass plates (if using a notched set, one notched and one unnotched back plate) for the appropriate gel height. Be sure the edges of the plates are nick or chip free. 2. It is vital that these plates are absolutely CLEAN ! Wearing gloves (and rinsing off any residual powder), clean the glass plates thoroughly with a non abrasive detergent and a plastic scouring pad. The cleaning solution should not leave a soap residue when rinsed thoroughly. 3.
3.4 Methods for sealing glass plate sandwich (A) Gel Slider™, ( B) Capillary Gel Casting or (C) Yellow tape (A) C.B.S. Scientific's Gel Slider™, Sequencing Gel Caster. This adjustable width unit simplifies the pouring of problem-free sequencing gels for the novice or experienced sequencer. Unit sold separately, see instructions for Gel Slider™ and skip section 3.5. (B) Capillary Gel Casting.
3.4 Methods for sealing glass plate sandwich - continued (A) Gel Slider™, ( B) Capillary Gel Casting or (C) Gel Sealing Tape (C) Gel Sealing Tape. Seal the sides and bottom of the assembled glass plate sandwich with gel sealing tape, as shown. Tape the sides first and then the bottom. Extend the tape around the bottom corners in both directions to ensure an adequate seal. Apply the tape as smoothly as possible to avoid forming air channels or bubbles along the edges of the glass plates.
3.5 Pouring the Gel 1. Always wear gloves, eye protection and protective clothing. 2. Prepare acrylamide gel solution using freshly made stock solutions or commercially available pre-mix solutions. See section 4.5 Buffers. Most gel formulations allow approximately 10 minutes before polymerization, so proceed quickly. Spacer thickness (mm) 0.2 0.4 0.5 0.75-1.0 Minimum volume required (ml) 50 65 90 120-180 3. Mix by gently swirling, using a magnetic spin bar on a stirring plate. Do not mix vigorously.
6. Before the acrylamide polymerizes, insert a comb into the top of the gel. The available types of combs are; rectangular tooth combs, a casting comb in the same thickness as a sharktooth comb or the back side of a sharktooth comb as a casting comb. If you are using a rectangular tooth comb, insert to edge of backing. If you are using a separate one well casting comb with a sharktooth comb, insert casting comb to edge of backing.
Section 4 Electrophoresis 4.1 Pre-electrophoresis 1. Remove the gel sealing tape from the bottom of the gel sandwich, if tape was used. Rest the bottom edge of the sandwich on the footing in the lower reservoir, notched plate inward. Using mounting clamps (Cat.# GPC-0001) attach the lower section of the glass plate assembly to the upright of the sequencer. Do not clamp glass plate assembly to the upper reservoir until the sharktooth comb is inserted. 2.
5. Verify that the upper buffer reservoir drain is secure. For the single 20cm wide sequencer, fill the upper buffer reservoir with approximately 350ml of electrophoresis buffer. Make sure no buffer is leaking from the upper buffer reservoir. Fill the lower reservoir with approximately 350ml of electrophoresis buffer. For the dual 20cm wide sequencer, fill the upper reservoir 375ml and the lower with 350ml.
4.3 Electrophoresis 1. After loading the samples, attach the reservoir safety cover. Connect the DC power leads to the unit then to the power supply with the proper polarity. Make sure the black leads are connected to the black cathodes (-) and the red leads are connected to the red anode (+). 2. Turn on the power supply and set the voltage or wattage to the proper setting for the gel. Be sure to follow manufacturer's instructions. (See Table 5.1 for recommended DC power settings).
4.4 Post-Electrophoresis – Gel Processing A. Removal of sequencing plate from gel unit. 1. Ensure power supply is OFF disconnect power cords from reservoirs. 2. Reduce buffer level in upper reservoir below level of notch (or drain entirely). If buffer is not reused, drain buffer from lower reservoir. Be careful with lower reservoir buffer, it will be radioactive if you have used 32P, 33P or 35S. Dispose of buffer according to your institutions radioactive safety policies.
B. Transfer of gel onto blotting paper-continued 2. Place a sheet of pre-cut (slightly larger than gel) blot/chromatography paper to fit on top of the gel and press down firmly and evenly over the entire gel surface. The gel will come off the glass and stick to the paper as you lift the paper/gel sandwich slowly and carefully away from the glass plate. NOTE: At this step, if you were using 35S you could follow the alternative fixing procedure given if greater band resolution is desired. 3.
4.5 Recommended Buffers and Reagents Pre-mixed acrylamide stock solutions are the method of choice. Use according to manufacturer’s instructions. EDTA solution (0.5 M EDTA, pH 8.0, 100ml) Na2EDTA•2H2O (FW 372.2) Deionized H2O Dissolve 10M NaOH. Adjust to pH 8.0. Deionized H2O Store at room temperature 0.5M 18.6g 70.0ml ∼5.0ml to 100.0ml Tris-borate-EDTA buffer, 5X (5X TBE, pH ∼8.3, 1 liter) Tris (FW 121.1) 0.45M 54.5g Boric acid (FW 61.83) 0.45M 27.8g EDTA solution (0.5 M, pH 8.0) 0.001M 20.
