Description: To prevent your waste canister from overflowing, connect these b.safe waste caps with electronic fill-level control to the alarm box. When the 'canister full' level is reached, you will receive an optical and acoustic warning. The alarm is triggered before your canister is completely full. This leaves a small safety buffer in the canister.

Description: Autoclaving is badly suited for the sustained removal of nucleic acids. DNA molecules in recombinant microorganisms are merely fragmented in the autoclave and subsequently released with the vapours when opening. By adding Autoclave-ExitusPlus™ to residual cultures or buffer solutions, the nucleic acids are effectively destroyed during autoclaving.

Supplier: Quantabio

Description: AccuStart™ II <i>Taq</i> DNA Polymerase is a high purity, recombinant <i>Taq</i> DNA polymerase preparation with high avidity monoclonal antibodies that bind the polymerase and keep it inactive prior to the initial PCR denaturation step. Upon heat activation (1 minute at 94 °C), the antibodies denature irreversibly, releasing fully active, unmodified <i>Taq</i> DNA polymerase. This enables specific and efficient primer extension with the convenience of room temperature reaction assembly. Non-specific extension of primers at low temperatures is a common cause of artifacts and poor sensitivity in PCR. The AccuStart™ II automatic hot-start enables specific and efficient primer extension in the PCR process with the added convenience of room temperature reaction assembly. The included 10X PCR Buffer II is a new optimised buffer that provides higher product yield, improved specificity, and enhanced multiplexing capability.
