Assay Questionnaire

ImmunoChemistry Technologies is a custom service laboratory specializing in immunoassay development and manufacturing. If you need to detect or measure a specific target molecule, we can fully develop a quick and accurate immunoassay test (or optimize an existing assay) according to your specifications.

In order to assess the feasibility of your project and generate an accurate quote, here are some questions we would typically ask you. Please either call us at 1-800-829-3194 to discuss your assay needs, or fax your responses to the Assay Questionnaire (952-888-8988). Responses are not necessary for all of the questions.

10. Is the assay for a one-time project, or will it be used for routine and on-going testing?:

a. How many samples will be tested overall?:

b. How many samples will be tested at one time?:

11. Where will the assay be used (in the lab or in the field)?:

12. Who will be running the assay (experienced scientists or non-technical people)?:

13. Do you have a microtiter plate reader or other instrument for reading the test?:

14. Does your test require FDA approval (or will it in the future)?:

15. Do you need GMP documentation?:

16. Is there any other information that may affect the design of the assay that you know of?:
