PCR/qPCR
MIDSCI can supply almost every needed product for PCR/qPCR: tubes, plates, strips, caps, taq, Mastermixes, dNPTs, dye and probe for qPCR, sealing film and much more. If you are looking for any of these things, we can match almost all needs to all cyclers. If you don’t find it easily contact us at tech@midsci.com and we will find it for you.
96 or 384 we have it. Non-Skirted, semi-skirted or full skirted, we have it. 0.1, 0.2, or 0.5 mL we have it. A1, A12, H12, A24, P24 cuts, we have them. Sybr© Green or probe alternative, we have it.
Pro Tip: Colored plastics do not have any impact on DNA amplification. But when setting up qPCR it is often recommended to use white plastics. This will limit or prevent fluorescence refraction. Light refraction can minimize sensitivity and consistency.
Pro Tip 2: If you are seeing inconsistencies in PCR/qPCR try PR1MA Pipette Tips. This will help optimize and reduce variance in the reactions. Simple test, see the residual liquid left in tips? This means some of the taq, dNTPs, sample, etc is left in the tip. PR1MA tips help reduce that significantly and improve your consistency.
Pro Tip 3: Seeing evaporation in the outer wells of a PCR/qPCR plate? Sometimes it’s the plate, sometimes it the seal, and sometimes it’s the cycler. Call us we have solutions.

General Description
Bullseye Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications. The enzyme is isolated from Thermus aquaticus and has a molecular weight of approximately 94 kDa.
Bullseye Taq DNA Polymerase has both a 5'®3' DNA polymerase and a 5'®3' exonuclease activity. The enzyme lacks a 3'®5' exonuclease activity (no proofreading ability). Taq DNA Polymerase leaves an A¢ overhang, which makes the enzyme ideal for TA cloning.

10X Mg++ Free Standard Buffer
100 mM Tris-HCl pH 8.3, 500 mM KCl.
Unit Definition
One unit is defined as the amount that incorporates 10 nmoles of dNTPs into acid-precipitable form in 30 minutes at 72°C under standard assay conditions.
Storage and Dilution Buffer
Enzyme is supplied in 20 mM Tris-HCl pH 8.3, 100 mM KCl, 0.1 mM EDTA, 1 mM DTT, 0.5% Tween 20, 0.5%NP40, 50% glycerol.
Quality Control
Each lot of Taq DNA Polymerase is tested for contaminating activities, with no trace of endonuclease activity, nicking activity, exonuclease activity or priming activity.
Suggested Protocol using Taq DNA Polymerase
This protocol serves as a guideline only. Optimal reaction conditions may vary and must be individually determined.
n In some applications, MgCl2 is needed for the best results. For this reason, 25 mM MgCl2 is included with the kit.
1. Thaw 10X Mg2+ Free Standard Buffer, dNTP mix, primer solutions. It is important to mix the solutions completely before use to avoid localized concentrations of salts.
2. Prepare a master mix according to Table 1. The master mix typically contains all the components needed for extension except the template DNA.

General Description
Bullseye R-Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications. R-Taq contains a red dye which provides easy and quick identification of reactions to which enzyme was added and allows confirmation of complete mixing. The inert dye has no effect on downstream processes. R-Taq is added directly to the reaction mix and is used in the same manner as standard Taq DNA Polymerase.
Bullseye R-Taq DNA Polymerase has both a 5'®3' DNA polymerase and a 5'®3' exonuclease activity. The enzyme lacks a 3'®5' exonuclease activity. R-Taq DNA Polymerase leaves an A-overhang, which makes the enzyme ideal for TA cloning.

Endonuclease, exonuclease and priming activities are not detected after 3 hours incubation of 1 mg of pUC19 plasmid DNA and 0.5 µg EcoR I digested lambda phage DNA at 72°C in the presence of 40 units of R-Taq DNA Polymerase.
Suggested Protocol using R-Taq Polymerase
This protocol serves as a guideline. Optimal reaction conditions such as incubation times, temperatures, and amount of template DNA may vary and must be individually determined.

2. Prepare a master mix according to Table 1. The master mix typically contains all the components needed for extension except the template DNA.
The optimal MgCl2 concentration should be determined empirically but, in most cases a concentration of 1.5 mM, as provided in the 1X Ammonium Buffer, produces satisfactory results. Table 2 provides the volume of 25mM MgCl2 to add to the master mix if a higher MgCl2 concentration is required.

Works as a plate seal (to eliminate cross contamination) and compression mat all-in-one!
Our compression molded 96-round plug, silicone sealing mats for PCR plates minimize sample evaporation in a wide range of temperatures. These mats are chemically resistant and reusable; containing no adhesives or extractables to contaminate samples. Made of research-grade silicone, they can be autoclaved, and following a 10% bleach wash and ethanol rinse protocol may be reused.
Wells are scored (cut 80% of the way through, but not all of the way) to allow for sample access via pipettor, syringe, or probe. These scored perforations will seal themselves, after penetration, ensuring an airtight closure to the well.These Rotocycler strips are perfectly designed to perform on Rotor-Gene instruments. Tube strips are packaged separately from cap strips. The frosted extensions on caps not only make them more efficient and secure during handling but also offer a convenient area for labeling. For individual use, tube and cap strips can easily be separated and used as individual units.

MaGELin Mini Protein System
- For 10 cm x 10 cm cast-your-own polyacrylamide gels
- Comes with dual casting system
- 3 sets of glass plates and 2 sets of 0.8 mm thickness spacers.
- Buffer tank, dual gel capture, vented lid and power cords included
The IB94000 MaGELin Mini protein system comes complete with everything you need to pour 10 cm x 10 cm cast-your-own gels. This highly versatile system will also accommodate the IB95000 Western Transfer module so when you’re not running gels the unit can be used as a dedicated Western transfer system.
The IB94000 comes complete with:
- Dual gel capture device for running two gels simultaneously.
- Dual gel casting system that allows casting outside of the running unit.
- Three sets of glass plates for pouring and running gels
- Two sets of special 0.8 mm side spacers to seal the gel sandwich during pouring
- Buffer tank
- Vented lid
- Power cords.
- Two 0.8 mm x 12-tooth combs.
The IB94000 utilizes a unique spacer and casting system to make it easy and fast to cast your own gels. The special side spacers are made specifically to accommodate the thickness of each glass slide that comes with the unit. These side spacers will produce a 0.8 mm thick gel. Once the glass plates have been assembled using the side spacers, they can now be inserted into the gel casting unit. This unit accommodates two sets of glass plates simultaneously. The bottom of the gel casting unit contains a very soft gel-like gasket that will seal the bottom of the gel sandwich. Once the gel sandwich is placed inside the casting unit, place the lid of the casting unit on top and press gently to fasten using the included thumb screws. Once fastened the lid will provide the correct amount of down pressure on the gel sandwich to seal the bottom and hold them in place. The polyacrylamide solution can now be introduced through the opening in the casting fixture lid.
Uniform white light diffusion for viewing negative and film positives. X-ray film, autoradiographs, microtiter plates, and stained gels can be viewed on the white light transmitting glass surface. This surface, permanently double-safety sealed into the unit for durability, provides a scratch and chemical resistant work area which can be cleaned easily. Durable transilluminator housing is scratch resistant, epoxy powder paint finish for easy cleaning. 2 year warranty
