Introduction

HiPure PCR Pure Micro Kit uses proprietary chemistry and HiPure technology to recover DNA fragments between 60bp-20kbp with yields exceeding 80%. DNA is suitable for ligations, PCR, sequencing, restriction digestion, or various labeling reactions. In addition, this kit can be also used to recover DNA directly from enzymatic reactions such as PCR and enzyme digestion reactions.

Principle

The HiPure system uses a simple bind-wash-elute procedure. Gel slices are dissolved in a buffer containing a pH indicator, allowing easy determination of the optimal pH for DNA binding, and the mixture is applied to the column. Nucleic acids adsorb to the silica-gel membrane in the high-salt conditions provided by the buffer. Impurities are washed away and pure DNA is eluted with a small volume of low-salt buffer provided or water, ready to use in subsequent applications.

Advantages

• High recovery efficiency – ≥80% DNA recovery
• Fast – isolation can be completed in 10 minutes by column gel method

DBCO-PEG4-Desthiobiotin is a PEG linker containing a desthiobiotin group and a DBCO functional group. Desthiobiotin is used for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins while DBCO is a click chemistry handle that quickly reacts with azide groups on target molecules. Desthiobiotin is a sulfur-free analogue of biotin which binds streptavidin with slightly less strength than biotin, which provides it with a soft-release characteristic that is useful for in pull-down assays by minimizing co-elution with endogenous biotinylated molecules. The inclusion of a PEG linker in this molecule improves its aqueous solubility.

Introduction

Usages：
Determination of coliform and fecal coliform for multiple tube fermentation.
 
Principle:
Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
 
Formulation (per liter):
Trypticase:20g
Sodium chloride: 5g
Lactose:5g
Potassium dihydrogen phosphate: 2.75g
Dipotassium hydrogen phosphate :2.75g
Sodium lauryl sulfate 0.1g
Final pH6.8 ± 0.2
 
How to use:
1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby .
2.Sample handling and dilution.
3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL.
4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h.
5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if  gas production then will have to make further confirmed by experiments.
 
Quality control:
Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows:
Bacterial Name                 Bacterial No.          Growth Status       Gassing
Escherichia coli                ATCC25922               good              +
 
Salmonella typhimurium        CMCC (B) 50115            good             —
 
Staphylococcus aureus          ATCC6538                inhibited          —
 
 
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
