Sell Silica Microsphere - China
price: contact company for price
The silica microspheres have found the special application of nucleic
acid isolation.
The breif introduction is as follows,
1 - The surface of silica microspheres carrys negative charges.
Putting microspheres into a solution of Ca2+ (or Mg2+) ions, with good mixing, then every negative charge will pick up a Ca2+ (or Mg2+).
This results in a positively charged surface.
2 - Wash the microspheres with very clean deionized water to remove excess Ca2+ (or Mg2+).
3 - Negatively charged DNA (or RNA) should then bind directly onto positively charged silica microspheres.
4 - Washing the silica microsphere to remove the impurities of sample
5 - Elute the DNA (or RNA) from the surface of silica microspheres; spin; remove the DNA (or RNA)-containing supernatant to clean tube.
Features 1．Uniform silica beads are easy to resuspend 2．Bead uniformity prevents shearing of high molecular weight DNA 3．Nonporous， ;no low molecular weight DNA (or RNA) loss 4 - Highly pure DNA (or RNA).
