Usages: For differentiating enteric bacteria based on urease activity by adding 40% sterile urea solution.
Principle: Peptone provides the carbon and nitrogen; maintain a balanced osmotic sodium chloride; potassium dihydrogen phosphate is buffers; decomposing bacteria urease urea medium, produce large amounts of ammonia, agar as medium coagulant.
Formulation (per liter): Peptone 1g Sodium chloride 5g Glucose 1g Ppotassium dihydrogen phosphate 2g Phenol red 0.012g Agar 12g Final pH7.2 ± 0.2
How to use: 1.Suspend 21g in 1L of distilled or deionized water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks. Autoclave at 121 for 15 minutes. cooling to 50-55 and adding 40% urea solution. 2.Diluted and treated samples.
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.

Sample amount
Tissue: <20 mgCells: <5 x 106
Yield
2-50μg
Elution volume
≥30μl
Time per run
≤25 minutes
Principle
This product is based on silica column purification. Remove paraffin by Buffer DPS. Sample lysis withproteinase K digestion requires only 15 minutes. After lysis, samples are incubated at 80ºC for 15 minutes. Transfer to an adsorption column and RNA is adsorbed on the membrane, while protein is not adsorbed andis removed with filtration. After washing proteins and other impurities, RNA was finally eluted with low-saltbuffer.
Advantages
Efficient DNA removal – one step RNA extraction can effectively remove genomic DNA
High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
Fast – the whole extraction only takes 15-25 minutes
Nontoxic – no toxic phenol chloroform extraction is required in the extraction

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.

Product Info
Description
ExcelTaq™ Klen-Taq DNA Polymerase is a specially blended enzyme mix containing KlenTaq-1 DNA polymerase (a 5’-exo-minus, N-terminal deletion of Taq DNA polymerase) and a small amount of a proofreading DNA polymerase. This unique blending helps to improve the fidelity, yield and processivity of the resultant PCR process. The Klen-Taq is also highly robust, showing high tolerance of varying concentrations of Mg2+; it is highly thermostable and has four times the fidelity compared to Taq DNA polymerase. The ExcelTaq™ Klen-Taq DNA Polymerase is ideal for DNA amplifications 0.5-5 kb in length on genomic DNA, and up to 10 kb on less complex templates.
Features
5’→3′ DNA polymerase activity
3’→5′ exonuclease activity (proofreading)
4× fidelity as compared to Taq DNA polymerase
Thermo-stable: up to 98°C during PCR denaturing step
Robust PCR performance, resistance to variance in PCR conditions
Storage
-20°C for 24 months
