摘要:
Sperm cells are stained according to processes that involve the combining of sperm cells with a fluorescent DNA selective dye at an elevated temperature in excess of about 40° C. The methods allow for a decreased staining time. The cells may thereafter be efficiently sorted according to common separation methods, including flow cytometry.
摘要:
Staining mixtures comprising viable spermatozoa, a composition which regulates oxidation/reduction reactions intracellularly or extracellularly, and a DNA selective dye are disclosed. The cells contained in such suspensions tend to have a greater capacity for enduring the various process steps typically associated with the sorting of sperm cells into gender enriched populations, thereby resulting in post-sort compositions with an increased number of viable or motile sperm. Processes for staining sperm cells comprising the formation of a staining mixture are also disclosed.
摘要:
Processes of storing sorted and unsorted spermatozoa, in the form of a sperm dispersion, having reduced motility relative to endogenous ejaculated sperm are disclosed. The immotile spermatozoa of the dispersion tend to have a greater capacity for enduring the rigors associated with storage, transportation, and fertilization procedures. Processes for providing such sperm dispersions, for inseminating a female mammal with such sperm dispersions, as well as compositions and combinations comprising the sperm dispersions, are also disclosed.

摘要:
This invention is directed to an improved process for the preparation of N-(phosphonomethyl)glycine (i.e., “glyphosate”), a salt of N-(phosphonomethyl)glycine, or an ester of N-(phosphonomethyl)glycine. The process comprises combining an N-substituted N-(phosphonomethyl)glycine reactant with oxygen in the presence of a noble metal catalyst. The N-substituted N-(phosphonomethyl)glycine reactant has formula (V): wherein R1 and R2 are independently selected from the group consisting of hydrogen, halogen, —PO3R12R131, —SO3R14, —NO2, hydrocarbyl, and substituted hydrocarbyl other than —CO2R15; and R7, R8, R9, R12, R13, R14, and R15 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, and an agronomically acceptable cation.

Sperm cell suspensions comprising a motility inhibitor are disclosed. The cells contained in such suspensions tend to have a greater capacity for enduring the various process steps typically associated with the sorting of sperm cells into gender enriched populations, thereby resulting in post-sort compositions with an increased number of viable or motile sperm. Processes for forming such cell suspensions, as well as processes for staining sperm cells, are also disclosed.
