Purification and characterization of human chorionic gonadotropin
FEBS Letters, 1971 Several investigators [2-71 have previously attempted to purify human chorionic gonadotropin (HCG). These methods proved to be either too time consuming, not reproducible, or limited to small quantities. In addition, these purified products are difficult to compare because of differences in the methodology of biological and physico-chemical ...

Functional parameters of spermatozoa obtained by a new selection device
FEBS Open Bio, EarlyView.This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.
