Volume: 25mL75mL175mL225mL

PRODUCT FEATURES

• The product is made of medical grade USP CLASS VI polymer polystyrene
• The product is made under a 100,00- class dust-free manufacturing site
• Two kinds of product line up are providing.

For adherent cell culture: Initial adherence and proliferative property of cells via hydrophilic surface treatment.

For suspension cell culture: The surface is resistant to cell adherence, which minimizes damage or loss of cell.

• Large mouthed design makes easy operation of pipet or cell scraper. The surface of flask is uniform and smooth, hence the clear view can be obtained when microscopic observation.
• The hydrophobic filter cap can prevent invasion of fungi and bacteria without water absorb.
• Gamma radiation sterilization
• Non Byrogenic Nase/Bnase free

Introduction

Usages:

For the rapid detection and enumeration of coliform bacteria.

Principle:

Peptone and yeast extract powder provides carbon and nitrogen sources and trace elements; sodium chloride maintains osmotic equilibrium; agar as medium coagulant; dodecyl sulfate inhibit Gram-positive bacteria; chromogenic substrate and large intestine flora β- galactosidase-glucosidase specific reaction, hydrolysis of the substrate, the release of the color groups  produce green colonies on the light yellow plate.

Formulation (per liter):

Peptone :10g

Yeast extract powder: 3g

sodium chloride:5g

sodium lauryl sulfate:0.1g

Agar :12g

Chromogenic substrate 2.7g

Final pH 7.0 ± 0.2

How to use:

1. Weigh 32.8g of this product, adding 1L of distilled or deionized water , heated to boiling stirring until completely dissolved, dispensing into flask without autoclaving.

2,Take 25g or 25mL of sample with aseptic procedures, added to the flask containing 225mL of sterile phosphate buffered saline (or saline) is shaken thoroughly homogenized with a homogenizer or a 1:10 dilution 1min, then 1:10 dilution continue to select the appropriate serial dilutions of three, two plates each dilution was inoculated.

3, the use of pour method: The medium is cooled in a water bath to about 50 , sterilized petri dish having a diameter 90mm, 1ml samples were inoculated per dish, then poured into about 15ml of the above dissolution medium, and mix to solidify, upside down, 37 for 24 hours.

4, using surface inoculation: cooled to about 50 , shake devoted to the medium in sterile petri dish. Can be stored in the refrigerator for a day or stored at room temperature for several days (dark, 4 ). The sample was streaked method or filter method, 37 for 24 hours.

5, observe the results.

Quality control:

This product appear light yellow after pouring into plate, these strains were inoculated after 36 ± 1 18 ~ 24h culture growth in the following table.

Growth of bacteria were cultured bacteria numbers feature

Escherichia coli ATCC25922 good green colonies

Citrobacter ATCC8090 good green colonies

Salmonella typhimurium CMCC50115 good colorless colonies

Enterococcus faecalis ATCC29212 suppressed —–

Storage: Store at 10-30 , dark, cool and dry place, tighten the cap immediately after use. Storage period of two years.

Introduction

HiPure Insect DNA Kits provides a simple and rapid solution for total DNA extraction of insect tissue samples. This kit is based on silica gel column purification technology without toxic phenol chloroform extraction and time-consuming alcohol precipitation. The whole extraction process only takes 30 minutes. HiPure Insect DNA Kit can process tissue samples less than 10mg at a time. Hipure Insect DNA 96 kit can process 96 insect tissue samples at a high throughput. The obtained DNA can be directly used in PCR, Southern blot, viral DNA detection and other experiments.

Principles

This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High purity DNA – can be used in sensitive downstream applications such as multiplex and quantitative pcr
• Fast – several samples can be extracted in less than 30 minutes
• Good repeatability – suitable for extracting high-yield DNA from insect tissue samples
• Safe – without phenol chloroform extraction and alcohol precipitation

Storage and Stability

Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 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. The entire kit can be stored at 2–8°C, but in thiscase buffers should be redissolved before use. Make sure that all buffers areat room temperature when used.
