Glass Microspheres 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 microsphere 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 microbead to remove the impurities of sample

5. Elute the DNA ( or RNA) from the surface of silica microbeads; spin; remove
the DNA ( or RNA) - containing supernatant to clean tube.


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) .
