PRYME PCR plastics are designed and optimized for PCR & qPCR applications.

Unique design and development provides maximum mold and manufacturing accuracy. We outline precise product specifications and tolerances and minimize mold cavities while using CYCLERtest's temperature control competence in our manufacturing process. Result: superior and reproducible products with, in case of (q)PCR vessels, an average wall thickness of 0.30 mm for tubes and strips and 0.35 mm for plates, both with a maximum tolerance of 0.05 mm. Combined with the identical design of (q)PCR product closure one ends up in fully interchangeable and freely selectable (q)PCR cap and vessel combinations.

Extreme uniform wall thickness leads to a very even heating of the sample and more homogeneous reaction conditions, leading to more reproducible results. Extreme uniform wall thickness also leads to lower evaporation rates and therefore more consistent (q)PCR results. Evaporation rates of >10% up to 30% significantly influence the ratio of your (q)PCR components in the vessel, and thus the resulting reaction and its result. In case of optical detection via optical reading through the side of the qPCR tubes, better wall uniformity increases the signal consistency.

Clever design and sealing bands around the tube closure points provide a leak-free seal, reducing evaporation and leading to more reproducible results. These superior sealing properties allow for running (q)PCR reactions with volumes as low as 5 µl. The cap design allows minimum pressure for closure and opening which is highly appreciated by users and minimizes RSI risks.

Protran nitrocellulose membranes are the most frequently specified transfer media in the world for a wide range of applications. Protran membranes are manufactured using 100% pure nitrocellulose to ensure the highest binding capacity possible. Other membranes referred to as "nitrocellulose" may actually contain large amounts of cellulose acetate, which will lower the protein binding capacity. In addition to high binding capacity, Protran nitrocellulose membranes inherently have very low background. The superior surface properties of the membrane guarantees superior signal-to-noise ratios, without the need for stringent washing conditions. Unlike PVDF membranes, Protran nitrocellulose requires no methanol pre-wetting step. This makes it the membrane of choice for proteins that prefer aqueous environments. Prior to transfer, the membrane is simply wet in water and then in the transfer buffer, with no other necessary pre-treatment steps. Protran membranes exhibit the best handling strangth of all pure nitrocellulose membranes.
Features:

  • High binding capacity (80-150g/cm2) of proteins and nucleic acids.
  • 100% pure nitrocellulose, with no cellulose acetate added, ensures the highest binding capacity possible.
  • Compatible with virtually all standard detection methods.
  • Low background - NC surface properties guarantee superior signal-to-noise ratios.
  • Triton-free matrix with low extractable levels will support the cell growth essential for colony blotting, plaque lifts, and tissue culture applications.
  • Available in many sizes and formats to fit different transfer devices and gel chambers.
