Embark Scientific LabTips

 bead assaysAre you using bead arrays or bead based technologies for DNA or Protein analysis? 

Experiencing low bead recovery can be frustrating!  If you are using a 200ul or even a 10ul pipette tip to draw off supernatant during wash steps, this could lead to significant bead loss.  The best method to draw off supernatant is with a plastic bulb pipet. The orafice is narrow and you have good control.  Also, a little goes a long way...leaving 10-20ul of supernatant in your tube during wash steps will help prevent losing your bead pellet.
