ReBlot Plus Antibody Stripping Solution, 10x

Brand:

Merck

Description

ReBlot™ Plus reagents efficiently strip probed blots of
bound antibodies. ReBlot™ Plus reagents are available
in two formulations, “Mild” and “Strong”.

• Re-Blot™ Plus Mild Stripping Solution – Provides
good results on both nitrocellulose and PVDF
membranes.
• Re-Blot™ Plus Strong Stripping Solution –
Performs when membranes with high signal are
to be stripped, or use when Re-Blot™ Plus Mild
treatment is not sufficient.

Key Benefits
• β-Mercaptoethanol-free to avoid pungent smells
• Room temperature stripping in only 15 minutes
• Fast reuse of blots for multiple antibody probings
• Non-acidic, for less risk of protein degradation
(such as in Edman degradation)

runDOC

Brand:

Cleaver Scientific

runDOC is a portable, lightweight gel documentation system designed exclusively for use with RunVIEW – the innovative new system designed for real-time size fractionation and recovery of nucleic acids. RunDOC comprises a darkroom hood and 12.1 megapixel digital camera to capture images of nucleic acid gels stained with EtBr, SYBR and runSAFE. The RunDOC darkroom hood is placed directly over the RVMSCHOICE gel tank located on the RunVIEW base unit, which includes an integrated power supply and blue LED gel illuminator. The blue LED illuminator provides the excitation source for the DNA gel located within the tank, and following excitation the light emitted is then visualized using either one of the bluVIEW lid options (supplied with RunVIEW and used with the RVMSCHOICE gel tank) or the RunDOC filter slide. RunDOC also benefits from a small footprint area, occupying minimal space within the laboratory.

runSafe

Brand:

Cleaver Scientific

RunSAFE is a non-mutagenic fluorescent reagent that produces instant visualization of DNA bands upon Blue Light or UV illumination of agarose gels. Supplied in 6X DNA Loading Buffer, CSL-runSAFE is used to prepare DNA markers and samples for loading on agarose or
polyacrylamide gels. It is the most sensitive stain available for detecting the double-stranded DNA (dsDNA). It contains three tracking dyes (Bromophenol Blue, Xylene Cyanol FF, and Orange G) for visually tracking the DNA migration during the electrophoresis process. It is ideal for the environment requiring a safe , non-hazardous alternative to Ethidium Bromide. Storage Store at 4°C up to 12 months. For longer periods, store at -20°C. runSAFE Dye is light sensitive and should be stored protected from light.

runVIEW

Brand:

Cleaver Scientific

Using RunVIEW is simple; first, cast a gel featuring two rows of wells with one matching pair of the preparatory combs supplied, before transferring the blue-light transparent gel tray to the MSCHOICE tank located on the base unit. Add sufficient buffer just to cover the gel, and remove the combs to load the DNA samples into the upper row of wells (loading tier). Replace the lid to connect the MSCHOICE tank to the integrated power supply before applying the voltage and switching on the blue LED gel illuminator. Watch through the bluVIEW lid viewing pane as the samples migrate in real-time to the second row of wells (extraction tier). Once the DNA bands of interest enter the tier, simply stop the power supply, remove the lid and harvest the DNA by pipette.

rvHOOD

Brand:

Cleaver Scientific

CSL-RVHOOD is a portable, lightweight viewing hood designed exclusively for use with RunVIEW – the innovative new system designed for real-time size fractionation and recovery of nucleic acids. It comprises a darkroom hood to help aid viewing of samples in a well lit room. The hood is placed directly over the RVMSCHOICE gel tank located on the RunVIEW base unit, which includes an integrated power supply and blue LED gel illuminator. The blue LED illuminator provides the excitation source for the DNA gel located within the tank, and following excitation the light emitted is then visualized using either one of the bluVIEW lid options.

S S Agar 500g

Brand:

Thermo ScientificTM OxoidTM

Isolate and identify Salmonella and Shigella species from clinical or food samples with Thermo Scientific™ Oxoid™ SS Agar (Dehydrated). Differentiation of Salmonella and Shigella is achieved by incorporation of lactose in the medium. Organisms which ferment lactose produce acid which, in the presence of the neutral red indicator, results in the formation of red colonies. Salmonella, Shigella, and other non-lactose-fermenting organisms appear as transparent or straw coloured colonies on SS Agar.
