BP-10 96-Well Plate Genomic DNA Isolation Kit (For Animal)

Kit Contents

• ACL Solution may form a precipitate upon storage. If necessary, dissolve the precipitate by warming the solution at 37ºC.
• Before use, add 2ml of sterilized water to the tube containing 40 mg of proteinase K, keep at -20 oC for long term.
• Before use, add 200 ml of 100% ethanol to 50ml Wash Solution.
• Elution Buffer is 2.0 mM Tris-HCl pH 8.0~8.5. Although TE buffer pH 8.0 or water can be used, yield is generally 10% lower.

Storage: With the exception of the Proteinase K, the kit may be stored at room temperature. The proteinase K should be stored at 4ºC for short term. The kit is stable for 18 months at room temperature. For longer storage, keep all contents cold.

Note: The purification method is based on centrifugation. There is a minimum height requirement of 75mm for apparatus to hold the assembly -- filter plate and deep well plate.

Principle:

This kit is designed for fast isolation of genomic DNA from animal tissues. The kit contains a membrane embedded in BP-10 96-Well Plate for binding genomic DNA each well. Nucleotides, proteins, salts, and other impurities do not bind to the Column. Purified genomic DNA can be applied in most molecular biology experiments including restriction digestion, PCR, Southern-blotting etc.

Applications:

Genomic DNA purification from different animal tissues.

Features:

• Preparation of high quality genomic DNA from variable sources.
• Rapid and economical.
• High yields
• No phenol / chloroform extraction , no ethanol precipitation

Procedure for Isolation of Genomic DNA from Variable Sources.

For Animal Tissue

1. Cut up to 30 mg tissue and place in Deep Well Collection Plate.
2. Add 300 ul of ACL Solution (Animal Cell Lysis Solution) to Deep Well Collection Plate and 20ul proteinase K, then seal.
3. Incubate at 55oC until the tissue is completely lysed (usually 1-3 hours). Occasionally vortex. Incubation in shaking water bath can reduce lysis time.
4. Cool to room temperature. Vortex for 20 seconds and Centrifuge 8,000rpm for 5 minutes.
5. Pipette 300ul of supernatant into a BP-10 96-Well Plate (if pellet not visible, repeat previous step) and add 300ul of AB Solution, Seal, Mix by occasionally inverting Plate, and keep for 2 minutes.
6. Place a 96-Well Plate on the top of a fresh Deep Well Collection Plate. Centrifuge at 6,000 rpm for 5 minutes with a rotor for microtiter plates.
7. Discard flow-through. Add 500 ul Wash Solution to each well of 96-Well Plate and spin at 6,000 rpm for 5 minutes. Discard flow-through and place BP-10 96-Well Plate back to the same Deep Well Collection Plate.
8. Add 500 ul Wash Solution to each well of the BP-10 96-Well Plate, spin at 6,000 rpm for 5 minutes. Discard flow-through and spin once more for 5 minutes to remove residue of Wash Solution.

10. Measure DNA quantity by UV absorption at A260 (1.0 OD unit is equivalent of 50 ug). Assess genomic DNA quality by an analytical 0.7% agarose gel. Isolated genomic DNA should not contain RNA. Its length should be over 50 kb.
