INTRODUCTION This application is for a NIGMS administrative supplement for equipment for the funded R01 grant. The parental funded grant number: 5R01GM127402-07 FAIN: R01GM127402 Principal investigator: Eugene Shakirov, PhD Project title: Genetic and epigenetic architecture of natural telomere length variation This application is directed to purchase the Azure Sapphire FL Phosphor Imager, the next generation of biomolecular imager. Through the use of laser excitation and photon multiplier tube (PMT) detection, Sapphire FL is able to scan storage phosphor screens with exceptional dynamic range and image quality. This piece of equipment is absolutely vital for the success of the project because it has features/capabilities essential for both aims in our research project. It will substantially speed up our progress while reducing costs in the long run.
