Rumen fluid samples were diluted 1 67,100 using LAL water pyrogen-free (LAL Reagent Water, Lonza Group Ltd., Basel, Switzerland), with the final dilution being made of 50% diluted sample and 50% β-glucan blocker (N.190, Lonza, Walkersville, MD, USA).
Diagnostic tools include anthropometry, bioelectrical impedance, dual energy radioabsortiometry and deuterium dilution, being the body mass and the lean mass indices the most frequently used parameters.
Finally, the suitability of the developed method was demonstrated through its application to the analysis of commercial personal care products (shower gels) without any sample treatment, only a simple dilution, being possible to determine the simultaneous presence of phthalates, parabens, and bisphenol A in almost all the gels analyzed.
After mechanical grinding (Pottere S, Biolab, Melcungen-Germany), 500 μL of homogenate was transferred into a tube containing 4.5 mL of 0.9% NaCl, and was used to perform four serial dilutions, the final dilution being 10-4.
To analyze motility, sperm are typically diluted in a capacitation permissive medium to between 10 and 10 per mL, with dilution being important for removing the effect of decapacitation factors.
Concerning desmin immunodetection, rabbit anti-mouse immunolobulins/TRITC (R0276) (Dako, Denmark) was used as secondary antiserum, 1 40 dilution being used, and 5% normal rabbit serum in PBS with BSA as normal serum.
