Study of Phytochromes by Optoacoustic Spectroscopy (CAT#: STEM-ST-0345-WXH)

Introduction

Phytochromes may function as light-regulated serine/threonine kinases, and can phosphorylate several substrates, including themselves in vitro. Phytochromes are phosphoproteins, and can be dephosphorylated by a few protein phosphatases.

Principle

Photoacoustic spectroscopy (PAS) is the measurement of the effect of absorbed electromagnetic energy (particularly of light) on matter by means of acoustic detection. The absorbed energy from the light causes local heating and through thermal expansion a pressure wave or sound.

Applications

Detect and quantify chemical functional groups and thus chemical substances
