NT8 User's Guide | Chapter 13: LCP Experiments

Once in place, tighten the plunger lock thumbscrew (located directly above the
plunger lock).

5.

Use the lever to dispense a small amount of LCP sample from the syringe to prevent
clogging and remove any air from the needle. Wipe the tip of the LCP syringe with a
chem wipe.

6.

The sensors on the NT8 will detect the presence of the LCP syringe. A dialog box will
open asking if you want to calibrate the syringe. Click

Yes

.

7.

Select the size of your LCP syringe and click

OK

. The NT8 will start calibrating the LCP

syringe.

Option 1: Set Up the Software Using the LCP Template

An LCP dispense template is preinstalled with your software. You may use it if you plan to
combine 800 nL well solution with 50 nL LCP drops. You must also use the MRC 2 Well
Crystallization plate as your well solution source.

To use this template:

1.

Click the

Open Task List

 button       .

2.

Open the Sample folder and select the

LCP 50 nL Monolein And 800 nL Well

Solutio

n task list.

3.

Click

Open

.

4.

Run your experiment by clicking the

Run Task List

 button       .

Option 2: Manually Set Up the Software

1.

Drag the LV Tip Caddy from the Plate Type library to LV Tip Caddy station image.

2.

Drag the LCP Plate Adapter from the Plate Type library to Microplate Station 1.

3.

Find the plate type you used for your well solution and drag the plate to Microplate
Station 2.

4.

Add the

Pick Tip

 command to the Task List by double-clicking the LV Tip Caddy

image.

5.

Click the

Repeat

 button               on the Task List to mark the beginning of tasks that

will be repeated for every column.

6.

Add the

Wash Tip

 command to the Task List by double-clicking the Wash Station
