Molecular Biology Reagents/Chemicals
MIDSCI™ gives you ultra-pure, cost-competitive molecular biology reagents and lab chemicals for life science research; often with significant cost savings over Sigma Aldrich and other lab reagent providers.
PR1MA™ Chemicals can help with a wide variety of research-based requirements.
Use our glycerol for polyacrylamide gel electrophoresis. Eliminate Agrobacterium after inoculation with the carbenicillin we carry. Or detect β-Galactosidase activity with X-GAL which, when combined with the IPTG we stock, can be used to detect lac gene expression in cloning applications.
We also carry Luria Broth (Lennox), for the propagation and maintenance of E. coli; DTT, in order to maintain –SH groups in a reduced state; and high gel strength agar for tissue culture and microbiological work.

Bullseye Agarose General Purpose
Bullseye Molecular Biology Grade Agarose is certified for use in standard electrophoresis procedures, including nucleic acid analysis, preparative electrophoresis, and blotting. This highly refined and purified agarose is produced under strict testing parameters to ensure lot-to-lot consistency. It features low electrophoretic mobility characteristics, making it ideal for a variety of applications.
Extracted from the cell walls of certain Rhodophyceae (agarophyte seaweeds), Bullseye Standard Agarose is a neutral polysaccharide composed of galactan, linked by agarobioses in a 1-3, 1-4 arrangement. This unique chemical structure enables agarose to form robust gels even at low concentrations. The gels exhibit a macroreticular structure with an open mesh, easily adjustable by varying the agarose concentration.
Bullseye Agarose GP2 offers
- General-purpose electrophoresis and blotting capabilities
- Excellent separation, resolution, and clarity
- Low absorption and background from staining reagents
- High gel strength for safe and easy handling

Bullseye Taq Plus Master Mix
- Pre-optimized ready-to-use PCR reagents
- Less pipetting to avoid contamination
- Quick and easy to set up
- Direct loading for electrophoresis
- Reproducible results
Users only need to add templates and primers, and water if needed. Extra 25 mM magnesium solution is also provided for additional fine adjustments. The Red Mixes contain a non-hazardous inert red dye. The purple mixes contain a non-hazardous inert purple dye. Completed PCR reactions utilizing the D124-R (red dye) or D124-P (purple dye) can be directly loaded into a well of agarose gel or other gels, for electrophoresis. No extra loading buffer is needed.
Storage: 4°C for up to one month, or -20°C for long term storage.
Magnesium Chloride: In general, 1.5 mM MgCl2 is recommended; this may vary with different conditions and primer sets. Some primers/templates may require adjustments for MgCl2 concentration, which can be achieved as shown below:
| Final MgCl2 concentration | 1.5 mM | 2.0 mM | 2.5 mM |
| Additional 25 mM MgCl2 per 50 uL reaction | 0.0 uL | 1.0 uL | 2.0 uL |
Directions for use: For a 50 uL reaction, use 25 uL of the Taq Master Mix, add template, primers, and water to a final volume of 50 uL. Cycling conditions vary for different templates and primers. To start with, try 30 cycles as follows: denature at 94°C for 30 seconds, anneal around 55°C for 30 seconds, and extend at 72°C for 1 minute / kb. After the PCR cycles, extend at 72°C for another five minutes to complete the PCR. Then store the reaction at 4°C.
1x Composition: 10 mM KCl, 20 mM Tris HCl (pH 9.0), 16 mM (NH4)2SO4, 0.1% Triton X-100, 1.5 mM MgCl2, 200 mM dNTPs, 2.5 units / 25 uL of Taq DNA polymerase, (optional: trace amount of red or purple dye) and enzyme stabilizers.
