¹Biology Department, University of Massachusetts Boston, ²Department of Bioengineering, University of California, San Diego

The goal of this protocol is to provide a straightforward and inexpensive approach to collecting Drosophila embryos at medium scale (0.5-1 g) and preparing protein extracts that can be used in downstream proteomic applications, such as affinity purification-mass spectrometry (AP-MS).

Teresa T. Liu^*1,2, Allison C. Rodgers^*3, Tristan M. Nicholson⁴, Jill A. Macoska^5,6, Paul C. Marker^6,7, Chad M. Vezina^6,8, Dale E. Bjorling^6,8, Alejandro Roldan-Alzate^2,9,10, Diego Hernando^10,11, Granville L. Lloyd¹², Timothy A. Hacker³, William A. Ricke^1,6

We describe the use of high frequency ultrasound with contrast imaging as a method to measure bladder volume, bladder wall thickness, urine velocity, void volume, void duration, and urethral diameter. This strategy can be used to assess voiding dysfunction and treatment efficacy in various mouse models of lower urinary tract dysfunction (LUTD).
