Sperm concentration (million/mL) was determined by using a digital photometer with auto dilutor (SMILE software, IMV Technologies, Paris, France).
The possible reasons of this uncertainty may be one or more than one of the following factors: (i) the condensation of high concentrated and temperature exhaust, (ii) reduction in pressure of high effective particle air (HEPA), (iii) preheating of primary dilutor to a temperature less than 195[degrees]C, (iv) variation in dilution ratio, (v) any problem in charging and collection mechanisms i.e., mishandling during particle charging, (vi) wrong inertial classification in a cascade impactor and (vii) the electrical detection of aerosol particles, etc.
The dilutor BTS (Beltsville Thawing Solution[R]), used in swine sperm, has been successfully used in cryopreserving fish sperm (FELIZARDO et al., 2010).
Sections were then incubated with Alexa Fluor 594-labeled goat anti-rabbit and FITC-labeled rabbit anti-rat secondary antibodies IgG at 1/100 dilutor for 2 hrs at RT.
El hematocrito (Hto) se determino por centrifugacion a 12000g durante 5 minutos, la concentracion de hemoglobina (Hb) por el metodo de cianometahemoglobina de Drabkin y los recuentos celulares en camara de Neubauer utilizando la solucion de Natt-Herrick como liquido dilutor (Fudge 2000).
BHF acted as a dilutor and lowered the interaction of the molecules; thus the tensile strength decreased.
