MicroCal iTC200

iTC 200

iTC 200 is an isothermal titration calorimeter. Isothermal titration Calorimetry is the standard for studying biomolecular interaction, which directly measures the releasing and absorbing of heat during a biomolecular event. The binding affinity (Ka), enthalpy change (ΔH) and binding stoichiometry (n) could be determined in a single experiment.

For more detail, please refer to MicroCal iTC200 brochure.

Important Notification:

*(2025-01-10) iTC200 is out of service beause of its washing module failure. Please ask BCF for manual operation procesures if you would like to use the instrument.

(2024-12-16) PEAQ-ITC Automatic system had an alignment problem and the syringe pipet could not dock correctly. Service is called. Sorry for the inconvenience.

*(2024-05-02) The 17-year-old iTC200 is available for Academia Sinica users only. Sorry for the inconvenience.

*(2024-04-01) iTC200 is out of service beause of slow response of its thermal core which might be caused by contamination from sample precipitates or simply aging of the instrument (16 years old). ITC samples can be submitted to our Automatic PEAQ-ITC. Sorry for the inconvenience.

*(2024-03-11) PEAQ-ITC Automatic system is available for service through BCF reservation system. Please review sample submission guideline before submit your sample.

* Do not shake, bang or knock the bench durining experiments.

* Do not plug or withdraw USB in the middle of a run; this causes system error and the experiment will be aborted by the control program.

* Do not analyze the data file that is not finished. Instead, copy the data file and analyze the copied data.

* The process for cleaning the injector syringe is modified, please ask Dr. Jao for the correct procedure.

* Use only 200uL PCR tubes provided by BCF (Rainin Cat#3-TC02-N). Some PCR tubes (ABgene cat.# AB-0337) do not fit the holder and the injector syringe may hit the bottom of the tubes.
