Phi29 Random Primer

Product Description

Phi29 Random Hexamer Primer is ready-to-use in strand displacement amplification of genomic DNA, plasmids, BACs, fosmids or phages.
Phi29 Primer contains modified nucleotides that are resistant to 3′-5′ exonuclease activity. We have developed proprietary purification procedure to ensure removal of DNA polymerase inhibitors. The concentration of Phi29 Random Hexamer Primer is optimized for amplification with Phi29 DNA Polymerase.

A method for the cell-free cloning of single DNA molecules without propagation in bacteria using phi29 DNA polymerase and our exonuclease-resistant Phi29 Random Hexamer Primer mix was developed by Clyde A. Hutchison, III, Hamilton O. Smith, Cynthia Pfannkoch, and J. Craig Venter (Synthetic Biology Group, The J. Craig Venter Institute) and published in PNAS.

DNA AMPLIFICATION

Reagent Quantity per reaction 
Template DNA 1 – 40 ng Phi29 Random Hexamer Primer 1 µL 2X Annealing buffer* 2.5 µL Deionized water to 5 µl.

Heat 3 min at 94°C, cool down, then combine with premixed:

Phi29 10X buffer 2 µL  Phi29 DNA Polymerase 5-7 units  dNTPs 4mM 2 µL  Deionized water to 15 µL

Volume 20 µL

  • Mix well by pipetting. Spin the sample briefly before placing in the thermocycler
  • Incubate at 30°C for 720 minutes. 
  • Inactivate polymerase at 65°C for10 min, keep at 4°C

To avoid extra DNA purification steps and ensure high sensitivity, you may use the following protocols for PCR and sequencing.

*2X Annealing buffer: 80 mM Tris-HCL, pH 8.0; 20 mM MgCl2

Cap the tubes and centrifuge briefly to collect the contents

Use the following cycling conditions:

  • Heat the plate at 94°C for 2 minutes
  • Repeat the following for 30 cycles:

Denature: 94°C for 30 secondsAnneal: Primer Tm – 5°C for 30 secondsExtend: 72°C for 0.3-1 min/1 kbMaintain the reaction at 4°C after cycling

CYCLE SEQUENCING
