For what reason do you want to measure in the eye?

I do not know any particular reason for measuring in an eye.

For general analysis you could try an ELISA method like http://www.enzolifesciences.com/ADI-900-204/angiotensin-ii-elisa-kit/

Hi Rajesh Choudhary,

If you only are interested in this protein and you have tissue-samples, I would use western-blotting or ELISA with appropriate controls. Which one is best, depends on your research question.

Good luck with your project.

Best regards,

Thanks everyone to your valuable suggestions.

Actually I have no idea about to mesearment but we think about ELISA method for detection.
