ABSTRACT

A method for the determination of selected amino acids in culture medium using HPLC with fluorescence detection is described. Twenty hours after intra-cytoplasmic sperm injection, one randomly selected zygote was transferred to the culture medium. After incubation (72 h after fertilization), the culture medium in which the embryo was incubated and blank medium was immediately stored at -80°C. Filtered medium samples were derivatized with ortho-phthalaldehyde (naphthalene-2,3-dicarboxaldehyde), forming highly fluorescent amino acids derivatives.
