Purify sequencing extension products from dye terminators, primers and other contaminants
Also purify DNA from different enzymatic reactions including restriction enzyme digests, Klenow reactions, alkaline phosphatase reactions, and ligations.
High recovery
Fast and efficient spin column format
Also available in 96 well format for high throughput
This kit provides a rapid spin column procedure for the purification and clean-up of sequencing and various other enzymatic reactions including restriction enzyme digests, Klenow reactions, alkaline phosphatase reactions, and ligations. The kit is used to remove reaction contaminants including dye terminators, salts, enzymes, excess primers and primer dimers. Contaminants are undesirable as they can interfere with many downstream applications including sequencing, RFLP, restriction enzyme digestions and ligation. Purification is based on spin-column chromatography without the use of phenol, chloroform or alcohol precipitation. The kit provides a high quality product with up to 90% recovery.
The kit is also available in a 96-well format for high-throughput sequencing reaction clean-up. Purification with the 96-well plate can be performed using either a vacuum manifold or centrifugation.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment.

For selective enrichment culture of Listeria monocytogenes in food.
Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; esculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.

Preparation
Suspend 57.4g in 1 L 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. Cool to 45-50℃,aseptically add the contents of 1 vial of Fraser Selective Supplement (SR0120) to each 225 mL of base to prepare FB1 solution; Add one reagent (SR0130) to each100 mL of FB2 culture medium to prepare FB2 enrichment solution.
Quality Control
Cultural characteristics observed after incubation at 35-37°C for 46~50 hours
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
Precautions
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Waste Disposal
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.
