Sigma Aldrich Fine Chemicals Biosciences The Belly DancerR orbital1EA
Whether your laboratory applications require gentle continuous agitation or vigorous mixing. The proven IBI Belly Dancer is your instrument of choice. The unique undulating motion of the Belly Dancer shaker is designed to provide the optimal movement for multiple applications in todays Life Science Research laboratory. The smooth combination of vertical and horizontal orbital motion allows for more rapid exchange of reagents in applications such as staining and de-stainign gels and promotes lower background in blotting techniques. The unique 3-dimensional motion and wide range of speeds also provides superior growth in multiple cell culture and tissue culture applications. The easily adjustable speed and platform pitch angle controls provide a wide range of agitation conditions from extremely gentle to vigorous. The Belly Dancer is an exceptionally simple liquid agitation system consisting of an orbiting platform flexibly anchored at four corners ao that the platform motion when a

Sigma Aldrich Fine Chemicals Biosciences SYBRR Green Quantitative R
The SYBR(R) Green Quantitative RT-PCR Kit combines Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV RT) JumpStart(TM) Taq DNA polymerase and SYBR Green I fluorescent dye in a one-step RT-PCR kit designed for measurement of gene expression. This convenient 2X ready mix includes M-MLV RT SYBR Green I dye JumpStart(TM) Taq DNA polymerase 99% pure deoxynucleotides buffer glass passivator and stabilizers. The JumpStart(TM) Taq DNA polymerase is an antibody-inactivated hot-start enzyme. Once the reaction temperature reaches 70C the DNA polymerase-antibody complex dissociates and Taq DNA polymerase activity is restored. This antibody-enzyme complex allows for easy and convenient set-up with less contamination risk than manual hot-start techniques.
Sigma Aldrich Fine Chemicals Biosciences beta Glucuronidase/Arylsul
-Glucuronidase/Arylsulfatase from Helix pomatiais is the most widely used enzyme preparation containing sulfatase activity and has a very broad specificity. It is a crude mixture of enzymes and the preparation does not involve any kind of chromatographic separation. This preparation contains both glucuronidase and sulfatase activity. Enzymatic hydrolysis prior to detection is essential for achieving high sensitivity during analysis. After hydrolysis the sample may be analyzed by mass spectroscopy gas chromatography HPLC or immunoassays. for doping analysis the sulfatase activity in addition to the glucuronidase activity is essential for the detection of all drug conjugates present in the sample. -Glucuronidase/Arylsulfatase is also used for the enzymatic hydrolysis of glucuronides and sulfate esters in biological fluids and primarily urine.
Sigma Aldrich Fine Chemicals Biosciences L Glutamne 13C515N2 98 at500MG
Glutamine is an amino acid with an uncharged polar side chain. It can be catabolized to glutamate and ammonia. Glutamine is the most abundant amino acid in the central nervous system. Isotope labeled amino acids are required for the production of isotopically labeled proteins.

Sigma Aldrich Fine Chemicals Biosciences RNAzolR RT for processing
RNAzol RT is a quick and convenient reagent for use in thesingle-step isolation of total andsmall RNA from biological samples of human animal plant yeast bacterial and viral origin. A convenient single-step liquid phase separation results in the isolation of RNA from DNA protein polysaccharides and other molecules. RNAzol(R) RT can be used to isolate separate fractions of mRNA and micro RNA or to isolate total RNA containing all classes of RNA in a single fraction. This product a mixture of guanidine thiocyanate and phenol in a monophase SOLUTIONon effectively dissolves DNA RNA and protein on homogenization or lysis of tissue sample. Addition of water to the mixture allows for the precipitation of DNA proteins polysaccharides and other molecules which can then be removed by centrifugation. RNA can then be isolated by alcohol precipitation washing and solubilization. Chloroform-induced phase separation is not necessary. One mL of RNAzol(R) RT is sufficient to isolate RN
