{AutoGenFlex 3000}

I.       Purpose:    To extract and purify genomic DNA from mouse tail and other types of animal tissues.

II.    Chemical Principal:  Proteinase K/phenol extraction method.

III. Pretreatment of Mouse Tail:

A.    Cut 5 - 10 mm of tail (about 10 - 30 mg).

B.    Place tail in 500l of a buffered Proteinase K solution (250l of AGF TD-M1 including 0.4mg/ml Proteinase K and 250l of AGF TD-M2).

C.    Incubate at 37C - 55C for 6 hours to overnight.

IV. Protocol Parameters:

A.    Sample Volume: 0.5ml of digest solution.

B.    Maximum Number of Samples: 40 samples per run (AutoGenFlex 3000).

C.    Processing Time: 3.4 hours for 40 samples (Includes 1 hour drying time)

D.  Yield: 20 - 60 g of purified DNA per 10 - 30 mg of mouse tail.

E.     Quality:    Typical OD260/280 values are 1.8
             The DNA is RNA free and can be used directly in downstream processes such as
                fluorescence DNA sequencing, PCR, Southern blotting and restriction endonuclease digestions.

IV.     Running the Protocol:

       A.    Load Reagents and Samples
         B.    Select a Protocol
         C.    Enter Number of Samples
         D.     Start the Run

V. Example of genomic DNA obtained from mouse tail.

mouse tail2.JPG (31940 bytes)A 10 mm sample (about 30mg) was pre-treated with proteinase K and loaded onto the AutoGen system for purification.  Approximately 2 mg DNA per mg of tissue was obtained with a purity of OD260/280 = 1.8 to 1.9.

 

VI.    Extraction and Purification Process:

Process Site Purpose System Process
1. Manual Digest Proteins Mix Proteinase K with Reagents AGF TD-M1 and AGF TD-M2 and add to sample, outside of the instrument.
2. Automated Precipitate Protein Add Reagent AGF TD-R7, mix and centrifuge.  Transfer supernatant to DNA tube.
3. Automated Precipitate DNA Add Reagent AGF TD-R4, agitate, centrifuge, discard supernatant.
4. Automated Wash DNA Add Reagent AGF TD-R5, mix, centrifuge, discard supernatant.  Repeat several times.
5. Automated Evaporate Alcohol Transfer DNA tube to incubation rack.
6. Automated Resuspend DNA Add Reagent AGF TD-R3, mix, and centrifuge.
