Pin Transfer of Compounds to Assay Plates

Seiko Compound Transfer Robot

The ICCB-Longwood currently utilizes three different instruments to conduct pin transfer operations. Each is used to transfer nanoliter volumes from compound storage plates into assay plates using stainless steel pin arrays (made by V&P Scientific).

Compound Transfer Robot

The Seiko is a cartesian robot that was custom designed and built at the ICCB-Longwood. This system is highly robust and can rapidly process many samples without requiring costly disposable tips. The steel pins are washed, sonicated in a water/methanol mix and dried with pressurized air. The robot is shown above. Click here for more details about compound transfer using this robot.

In addition the Seiko has been integrated with a TwisterII robotic arm from Caliper. Click on the link below to see a brief video of the Seiko working with the TwisterII.

Epson Compound Transfer Robot

The Epson compound transfer robot, is a custom design similar to the Seiko robot setup. The pin arrays are calibrated to transfer 100nL and are then washed with a flow through methanol cycle as well as an air dry station. A sonicating bath will be added in the future to more closely mimic the wash cycle of the Seiko robot.


Pin Arrays

We have both 96- and 384-well pin arrays.  The pin arrays allow transfer of 300nl, 100 nl, or 10-20 nl volumes, depending on pin diameter.  Click here for more information about pin arrays and selecting a pin array for your screen.



CyBio CyBi-Well vario System

CyBio CyBi-Well vario System

In addition to being a low-speed, high accuracy liquid handling device (click here for details), the CyBio CyBi-Well vario was upgraded to perform pin-transfer operations. Currently, 10-20nl and 100nl pin arrays are available. Calibrations performed by the staff indicate that the 100nl pin array transfers virtually the same quantity as that of the Seiko pin-transfer robot’s 100nl pin array. The CyBi-Well vario, like the Seiko, also washes with methanol; however, the pins are then blotted and air-dried at the end of the wash cycle.
