Nucleic acid extraction apparatus based on the Tajima pipette (see Fig. 2) are one of the most widespread instruments to perform the Boom method.
The Tajima pipette was invented by Hideji Tajima, founder and president of
Precision System Sciences (PSS) Inc., a Japanese manufacturer of precision and measuring instruments.
Tajima pipette is a Core Technology of PSS Inc.
PSS Inc. provides OEM product based on this technology (for example MagNA Pure(R) )
for several leading reagent manufacturers such as Hoffmann-La Roche, Life Technologies, ... and so on.
After the Tajima et al. patent was filed, similar patent applications have also been filed by other parties.
The Tajima pipette performs magnetic particle control method and procedure, which can separate magnetic particles combined with a target substance from the liquid by magnetic force and suspend them in a liquid.
