Sigma Aldrich Fine Chemicals Biosciences PlateFugeTM Microplate Mic1EA
The Benchmark Scientific C2000 PlateFuge is the first mini sized centrifuge with a swing out rotor for micro plates. Centrifuging plates before PCR ensures all reactants are in the bottom of the wells for proper concentrations and improved yields. In spite of its remarkably small footprint (9x10 inches) the PlateFuge includes a uniquely designed swing out rotor capable of securing 2 micro plates. The easily accessible rotor chamber of the C2000 includes two plate carriers that rest at a 75 degree angle. This allows plates to be inserted confidently without sealing tapes or caps. Upon closing the lid of the centrifuge the rotor accelerates and the centrifugal force swings the plates into a horizontal position. Any droplets on the walls of the plate quickly concentrate into the well bottoms. With a g-force of over 400 xg most samples can be spun down in less than 20 seconds. To end a run simply open the lid and the automatic electric brake brings the rotor to a quick smooth stop i
Sigma Aldrich Fine Chemicals Biosciences SynthwareTM all glass vacu1EA
With 4 mm double oblique high vacuum solid glass stopcocks precision ground with corresponding numbers on barrel and plug. Solid glass stopcocks have constant pressure retention devices. Beams are 22 mm O.D. with front-left and rear-left-right 10 mm hose connections. Distance between stopcocks is 75 mm center to center.
Sigma Aldrich Fine Chemicals Biosciences DuranR double walled jacke1EA
The DURAN double walled wide mouth bottles GLSA80 incorporate an integral jacket that isolates the contents from the external environment. Heated or cooled liquids can be circulated through the jacket to control the temperature within the screw topped DURAN bottle. The DURAN double walled bottles offer a sealable and more flexible alternative to open topped jacketed beakers.

Sigma Aldrich Fine Chemicals Biosciences dCas9-3XfLAGTM-Biotin Prot
Recombinant dCas9-3X fLAG-Biotin protein from Streptococcus pyogenes (~165 KD) is a ready-to-use reagent for genome engineering and genomic DNA detection isolation and imaging experiments. When combined with target-specific guide RNAs dead Streptococcus pyogenes Cas9 protein acts as a DNA targeting protein suitable for transfection of cell cultures microinjection DNA pull-down chromatin enrichment microbial identification and in situ DNA imaging. At the C terminus the protein is tagged with a SV40 large T antigen nuclear localization signal (NLS) for nuclear import and both a 3XfLAG epitope and biotin for anti-fLAG(R)-based or streptavidin-based experiments.

Sigma Aldrich Fine Chemicals Biosciences Riboflavin Binding Protein10MG
Riboflavin binding protein (RBP) transports riboflavin through the bloodstream of the laying hen into the eggs where the vitamin is essential for embryonic growth and development. RBP consists of a single polypeptide chain containing 9 disulfide bonds. It is a glycoprotein containing ~14% carbohydrate with sugar moieties including galactose mannose and glucosamine and is phosphorylated.
Sigma Aldrich Fine Chemicals Biosciences fastStartTM High fidelity
The fastStart(TM) High fidelity PCR System is a blend of fastStart Taq DNA Polymerase and a thermostable proofreading protein which is also chemically modified. This protein mediates proofreading activity but carries no polymerase activity. Both proteins are inactive below 75 C and are activated by heating to 95 C for two minutes.Hot start protocols have improved specificity sensitivity and PCR yield. Heat-labile blocking groups on amino acid residues of fastStart(TM) Taq DNA Polymerase make the enzyme inactive at room temperature. There is no elongation at low temperatures when primers bind nonspecifically. fastStart(TM) Taq DNA Polymerase is activated by removal of blocking groups using a preincubation step at 95C. The fastStart(TM) High fidelity PCR System is the product of choice for multiplex PCR. fastStart(TM) High fidelity Enzyme Blend (5 U/mul) in storage bufferfastStart(TM) High fidelity Reaction Buffer 10x concentrated with 18 mM MgCl2fastStart(TM) High
