4 1. Introduction The Cycler TCY pr ovides the researcher w ith t he means of accurately controlling the temperature profile of samples. It has many scientific applications, including DNA amplification and sequencing. The Cycler TCY can cycle samples between 4°C and 99°C. The Cycler TCY is programmed by me ans of an integral keypad and LCD displa[...]

5 Unpacking When unpacking please ensure that the fo llowing have been removed from the packaging:  Thermal cycler  Power cable The user is advised to keep the original packaging in case the instrument ever needs to be returne d for service or repair.

9 The amount of volume loss you observe and the change in reactant concentrations you can tolerate determine the minimum volume that can be used . Typical volume losses of 1µl in 30 cycles allow the use of samples of 20µl or less. During the final cool-down, a ring of condensation ma y form above the liquid level but below the top of the sample b[...]

10 Switching on When you switch on the unit a s creen similar to the one shown here w ill a ppear briefly. This indicates the software version and block type installed in the unit.

15 Programming Options There are two options available for creating programs on the CYCLER: 1. Copy and edit one of the pre-written temp lates. 2. Create a new program from the defaults. Option 1: Creating programs using templates There are two pre-w ritten basic PCR templates: a tw o-step and a three-step temp late. These can be copied and modifie[...]

16 A new name can now be given to the copied program (see below). To give a program a name To type in a name for the program, press "Enter" and a cursor will appear in the position shown. Using the key pad, type in the name you wish to give the program. The letters will scroll round with successive presses; for example the “2” key wil[...]

17 To edit a field or step in an existing program When the unit is switched on the display will show this screen. If known, type in the ‘Speed dial’ number for the required program and press “Enter” This will take you directly to the required program. If you do not know the ‘Spe ed dial’ number, press “Enter” to access the list of s[...]

18 To edi t a temp erature, type in the requ ired temperature. In the example here, the heated lid t emperature is being edited. Press “Enter” to accept. Use the “Down Arrow” and/or t he “Up Arrow” keys to select the next field or step you wi sh to edit. To edit a field with on/off settings, first select the field and pres s “Enter”[...]

19 To cop y a selected pr ogram If you select ‘Copy program’ a screen similar to this w il l appear and the software will automa tically give the program the next number until it is na med. Press “Enter” and type in a new name. You will then be able to edit the program as previously desc ribed. To delete a selected program If you select ‘[...]

32 9. Notes on transfe rring protocols from ot her thermal cy clers The CYCLER TCY heats at over 3.6°C/s and provides the highest levels of temperature unifor mity. Many slower machines have historically begun the countdown on hold times before the set temperature is reached in ord er to avoid any overshooting in sample temperature. The slower the[...]

33 10. User maintenance Cleaning your CYCLER The heating/cooling block, including wells and flat surfaces, should be cleaned regularly to ensure optimum heat transfer to the sample s. Always clean the block if the re has been a spillage. Use a cloth or cotton buds dipped in a fresh, 50 :50 water/is opropanol solution and ma ke sure that no deposits[...]

34 11. Some frequent ly asked questions Q1 What is the ‘Pause’ function at the s tart of the program used for? A1 Some users prefer to pre heat the heated lid before plac ing the samples into the unit. The pause fea ture is used to stop the unit a fter the 4 minut e heated lid preheat step. It will also sound an audi ble alarm indicating that t[...]
