- Supplied with 6x sample loading buffer
Bullseye 100bp DNA Ladder consists of 11 DNA fragments ranging in size from 100-1500 base pairs (bp). 6µl will yield at least 30ng DNA in any single band. The intensity of the 500bp band has been increased to serve as a reference for easy identification.
Size: 1200µl
Storage: Store at -20°C.
Concentration: 500ng/6µl
Loading Buffer Composition:
10mM Tris-HCl
1mM EDTA (pH 8.0)
0.02% Bromophenol blue
0.02% Xylene cyanol
5% Glycerol
Usage: Add at least 6µl Bullseye 100bp DNA Ladder directly to wells designated for markers. You may need more than 6µl of ladder, depending on well size and level of intensity needed to visualize the bands.

SealPlate® RollMate™ Pre-scored Film in a Convenient, Easy to Use Roll Format
Pre-scored film on a roll is a more economical and efficient alternative to rapidly seal microplates or racked test tubes; faster than applying single sheeted film. Self-standing, non-slip supports hold the pre-scored film roll securely in place for quick and easy bench-top dispensement. The roll unwind tension can be easily adjusted to user preference. Continuous backing liner can be torn off or fed directly into a waste basket for disposal.
- Economical
- Quicker, more efficient sealing
- Provides a secure seal and is easy to remove
- Rigid polyester film features good clarity and easy handling
- Can be used as a temporary seal while awaiting further processing
- General laboratory use
- Short-term storage
- Incubation
- ELISA
- -40°C to +120°C
EZcap™FoilStrips
An economical and more user-friendly alternative to PCR strip caps; no sore thumbs and fingers guaranteed!
- Certified DNase- & RNase- free
- Each sheet contains 6 strips on a continuous liner for ease of use
- Pierceable with a pipet tip or robotic probe for direct sample recovery
- The conformable nature of foil allows for the visual verification of the seal’s security around each well
- 2.0mil aluminum foil removes easily without tearing
- A non-locking workstation is recommended for sample prep (e.g. 96-well round-boom plate)
- Removal of the end-tabs at the perforations is recommended before cycling
- A final sealing step is highly recommended in the thermal cycler because 8-tube strips flex during handling
- Do not fold foil around sides of tubes

Silicone Sealing Mat for 96 plates
- Made of research-grade silicone
- Scored wells for sample access
- Perforations re-seal after access
- Resists coring and tearing
- Eliminates cross-talk between wells
- Also works as a compression mat
- Suitable for standard PCR thermocycling
- Mats can be reused
- For use with 96-well PCR plates
- Printed alpha numeric grid for easy reference
- Certified to be free of RNase, DNase, DNA, PCR inhibitors, and Pyrogen contamination.
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.
- The CleanSpot is designed to fulfill a very important laboratory need...control of PCR contamination.
- Just 25 - 30 minutes of UV irradiation in the CleanSpot can prevent unwanted PCR contamination.
- The combination of a special light reflector and two powerful overhead UV bulbs generate Pyrimidine Dimers (T,C) and other photo defects in contaminating target sequences, thus eliminating falsely primed products that result in countless lost time and expense.
- The CleanSpot is designed to prevent unwanted contaminant DNA in amplification mixtures, thereby saving many lost hours and expensive samples.
- The UV resistant acrylic enclosure provides a contained, dead air space in which to set up your reactions and permits safe 254nm UV irradiation of solutions and supplies. This powerful UV wavelength renders DNA contaminants biologically inactive in 30 minutes or less.
- The thick front panel is an effective beta irradiation shield as well as acting as a breath guard. An overhead fluorescent light illuminates the work area.
- Dimensions: 18"L x 24"W x 28"H
- 1 year warranty
AlumaSeal® CS™
- Specially formulated for cold storage to -80 °C
- Excellent barrier properties to retard evaporation
- Easily pierceable with pipet tips or robotic probes for sample recovery
PR1MA™ Cod Uracil-DNA Glycosylase
PR1MA™ Cod Uracil-DNA Glycosylase (cUNG) is a recombinant, thermolabile enzyme that removes uracil from DNA. It is ideal for preventing carry over contamination during RNA or DNA amplification reactions that substitute dUTP for dTTP. cUNG is the only commercially available UNG that is completely and irreversibly inactivated by moderate heat treatment, unlike bacterial versions of the enzyme. Cod UNG treatment in combination with targeted pre-amplification using dUTP provides a simple and efficient solution to eliminate carry-over contamination and the generation of false positives and inaccurate quantification.
- Optimal temperature: 37°C
- Heat inactivation: 55°C for 5 minutes
- Enables contamination control in PCR and other amplification methods
- Does not degrade product after inactivation, enabling downstream use of the amplicon
- Storage temperature: -20°C
Buffer composition
- 50% glycerol
- 50 mM Tris-HCl
- 50 mM KCl
