The molecular composition of raw milk (RM) was assessed for refrigerated samples, which were prepared by diluting 0.01 mL of milk with 0.99 mL of deuterated (99.8%D2O/H2OO, Armar Chemicals) phosphate buffer (90 mM, pH 6.5).
The Pittsburgh business unit then sent the refrigerated samples to the appropriate Nichols site.
Even though samples were collected as clean as possible, changes in lactate and citrate were identified in the refrigerated samples, which suggest microbial contamination.
For the samples stored in DMEM at 37 °C, we observed a significant reduction of RCI compared with the fresh and refrigerated samples (54.4 ± 1.76 %; p ≤ 0.001).
Lactate dehydrogenase (LDH) was measured within 24 hr on refrigerated samples with a COBAS MIRA Plus analyzer (Roche Diagnostics, Indianapolis, IN) using kits from Roche.
Lactate dehydrogenase (LDH) and albumin were measured within 24 hr on refrigerated samples with a COBAS MIRA Plus analyzer (Roche Diagnostics, Indianapolis, IN) using kits from Roche Diagnostics and Sigma-Aldrich (St . Louis MO), respectively.
Upon arrival at the laboratories, frozen specimens were initially stored at -20°C, refrigerated samples were stored at 4-8°C 4-8°Cfrozen specimens with delandd analysis were stored at -70°C or lower [ 21].
Although some sperm survive past 24 hr (Stovall et al. 1994) and refrigerated samples maintain sperm chromatin structure (Morris et al. 2003), our next-day motility and straw end points were exploratory, given the absence of established validity for interpreting findings as with clinical semen analysis.
At the anti-doping organization's request, Dr. Catlin's lab retested 550 refrigerated urine samples.
In contrast, the isolation of Ma in refrigerated milk samples was compromised by the presence of BR, and in smaller measure by the treatments AZ and NP.
