| Description
| - Pro účely zmrazování spermatu veslonosa amerického bylo využíváno sperma s minimálně 80 % pohyblivostí. Různé procento čistého kryoprotektoru (metanol nebo DMSO) bylo přidáváno k extendoru obsahující 20 mM trisu pH 8 + 30 mM sacharózy + 0.5 mM KCl, při ředění se spermatem 1:1). Vždy 1 ml ředěného spermatu byl pipetován do 2-ml kryo-zkumavek. Kryo-zkumavky se umístily do předem na programovaného zmrazovacího automatu PLANER Kryo 10 série III s výchozí teplotou 0 oC a zmrzováno z 0 oC do -5 oC rychlostí 3 oC.min-1, z -5 oC do -15 oC rychlostí 5 oC.min-1, z -15 oC do -25 oC rychlostí 10 oC .min-1, z -25 oC do -80 oC rychlostí 20 oC .min-1, následně uchováváno po dobu 5 min při -80 oC a finálně přeneseno do kapalného dusíku. Zmrazené sperma se rozmrazovalo při 40 oC po dobu 105 s. Procento motility u rozmrazených spermií 20 s po aktivaci bylo signifikantně nižší než u čerstvého spermatu. Nejlepší kryoprotektant se jevil 8 % methanol s úrovní oplozenosti 61-76 % při použití 3,6.105 spermií na jednu jikr (cs)
- A sperm cryopreservation method using different cryoprotectants and sperm from different males was developed. Different percent of pure cryoprotectant (methanol and DMSO) was added in extender 1 or 2 (20 mM tris pH 8 + 30 mM sucrose + 0.5 mM KCl or 20 mM tris pH 8 + 50 mM sucrose + 0.5 mM KCl, dilution 1:1) or non-extended sperm and every 1 ml of mixture was transferred to a 2-ml cryotube. The cryotubes were directly transferred to a pre-programmed PLANER Kryo 10 series III at 0 oC and cooled from 0 oC to -5 oC at a rate of 3 oC.min-1, from -5 oC to -15 oC at a rate of 5 oC.min-1, from -15 oC to -25 oC at a rate of 10 oC .min-1, from -25 oC to -80 oC at a rate of 20 oC .min-1, then held for 5 min at -80 oC and finally transferred into LN2 until next morning. The sperm was thawed in a water bath at 40 oC for 105 s. Fertilization rate of control sperm (unfrozen) samples after 24-h storage at 3 oC was 81.5 % it indicated that the gametes were of good quality. Percentage and the velocity of motile sperm
