Electrophoresis Equipment. Electrophoresis equipment applies an electric charge to molecules, causing them to migrate towards their oppositely charged electrode. The technique is found in all research and clinical laboratories utilizing DNA and protein applications, and is divided into gel and capillary techniques.lectrophoresis Equipment.

primary spermatocyte a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes. secondary spermatocyte one of the two haploid cells into which a primary spermatocyte divides, and which in turn gives origin to spermatids.
Spermatogenesis is the process in which an animal produces spermatozoa from spermatogonial stem cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis. The primary spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte divides into two spermatids by Meiosis II. These develop into mature spermatozoa, also known as sperm cells. Thus, the primary spermatocyte gives rise to
