Description

High RT Kit includes a recombinant genetically engineered version of a thermostable M-MULV reserve transcriptase Since this is more thermostable than M-MLV, the synthesis cDNA is possible over 50ºC and this is modified enzyme shows an optimal activity at 50ºC. In addition, the synthesis of cDNA is achieved efficiently because 2nd structure of RNA can be retarded more easily comparing to that in low temperature.

Cat Number : BR1041
Description

M-MLV Reverse Transcriptase (RT) is a genetically modified M-MLV RT. It differs from the M-MLV RT by its structure and catalytic properties. The enzyme possesses an RNA-dependent and DNA-dependent polymerase activity and a ribonuclease H activity specific to RNA in RNA-DNA hybrids.

Description
All applications for agarose take advantage of the specialcharacteristics of the marcoreticular gel. It is used as a sieve or support through whichbiological macromolecules such as proteins or nucleic acid can pass. Larger particles,such as viruses and subcellular fragments,are also able to move through the gelnetwork.Agarose LE is optimized for pulsedfieldelectrophoresis. This product has anexceptionally low EEO and high gel strength,both of which facilitate the preparation of low concentration gels for resolving Largefragments (>20kb). Gel strength (1.5%)>2200g/cm2.

Discription

GoodView TM is a new nucleic acid stain, an alternative to the traditional ethidium bromide (EB) stain for detecting nucleic acid in agarose gels. It emits green fluorescence when bound to DNA or RNA. This new stain has two fluorescence excitation maxima when bound to nucleic acid, one centered at 268 nm and another at 294 nm. In addition, it has one visible excitation at 491 nm. The Fluorescence emission of GoodView TM bound to DNA is centered at 530 nm.

Protocol
1. Prepare 100 ml of agarose gel solution (concentration from 0.8~3%) in a 250 ml flask and mix it thoroughly. Place the flask in the microwave, heat it until the solution is completely clear and no small floating particles are visible (about 2~3 minutes).
2. Add 2-5ul of GoodViewTM to the gel solution. Swirl the flask gently to mix the solution and avoid forming bubbles.
3. While the gel solution cools, pour it into the gel tray until the comb teeth are immersed about 1/4~1/2 into the gel solution.
4. Allow the agarose gel to cool until solidified. Load samples on the gel and perform electrophoresis.
5. Detect the bands under UV illumination.

Store at 4℃ for 2 years
Comparative sensitivity test of GV and EB
1. Sensitivity test of GoodViewTM Nucleic Acid Stain Template：5～70 ngλDNA（λDNA diluted to different concentrations） GoodView：add 5 μlGoodView to 100 ml 1% agarose gel solution.
2. Sensitivity test of EB Template：5～70 ngλDNA（λDNA diluted to different concentrations） EB：add 5 μl EB (10 mg/ml) to 100 ml 1% agarose gel solution, to make the final concentration to 0.5 ng/μl.



The result of electrophoresis demonstrates GV is almost as sensitive as EB.

Description
The TRAzol RNA Purification Kit provides a simple, reliable, and rapid method for isolating high–quality total RNA from a wide variety of samples, including animal and plant cells and tissue, bacteria, and yeast. The kit utilizes the strong lysis capability of TRAzol Reagent. TRAzol Reagent maintains the integrity of the RNA, while disrupting cells and dissolving cell components. Addition of chloroform followed by centrifugation, separates the solution into an aqueous phase and an organic phase. RNA remains exclusively in the aqueous phase. After transfer of the aqueous phase, the RNA is recovered by precipitation with isopropyl alcohol. After removal of the aqueous phase, the DNA and proteins in the sample can be recovered by sequential precipitation. Precipitation with ethanol yields DNA from the interphase, and an additional precipitation with isopropyl alcohol yields proteins from the organic phase. Copurification of the DNA may be useful for normalizing RNA yields from sample to sample. Total RNA isolated by TRAzol Reagent is free of protein and DNA contamination. It can be used for Northern blot analysis, dot blot hybridization, poly (A)+ selection, in vitro translation, RNase protection assay, and molecular cloning.

Cat Number : BC0473A
Description
A major application for Ribonuclease A (RNase A) is the removal of RNA from preparations of plasmid DNA. In this application, the presence of DNase activity as an impurity is a concern. The boiling-water bath method used to eliminate contaminating DNase activity has proven unreliable. For this reason, developed a proprietary chromatographic preparation method for elimination of DNase activity.

RNase A is an endoribonuclease that attacks at the 3¢ phosphate of a pyrimidine nucleotide. The sequence of pG-pG-pC-pA-pG will be cleaved to give pG-pG-pCp and A-pG. The highest activity is exhibited with single stranded RNA. RNase A is a single chain polypeptide containing 4 disulfide bridges. In contrast to RNase B, it is not a glycoprotein. RNase A can be inhibited by alkylation of His12 or His119 , which are present in the active site of the enzyme. Activators of RNase.

Molecular mass: 13.7 kDa (amino acid sequence)
Extinction coefficient: E1% = 7.1 (280 nm)
Isoelectric point: pI = 9.6
Optimal temperature: 60 °C (activity range of 15–70 °C)
Optimal pH: 7.6 (activity range of 6–10)
Inhibitors: ribonuclease inhibitor
The chromatographically purified product is supplied as an essentially salt-free lyophilized powder.
Activity (Kunitz): ≥60 units/mg protein.
Storage/Stability
This product remains active for at least 3 years when stored properly at –20 °C. RNase A is a very stable enzyme and solutions have been reported to withstand temperatures up to 100 °C. At 100 °C, an RNase A solution is most stable between pH 2.0 and 4.5.

Procedure
A major application for RNase A is the removal of RNA from preparations of plasmid DNA. For this application, DNase free RNase A is used at a final concentration of 0.2 mg/ml.
