The phrase "assays of the second" is not a standard expression in written English and may be unclear without context.
It could potentially be used in scientific or technical writing, particularly in contexts involving analysis or testing related to a second sample or time frame.
Example: "The results from the assays of the second sample indicated a significant increase in the compound's concentration."
Alternatives: "tests of the second" or "analyses of the second".
In mid-January 2008, antiviral susceptibility testing (enzyme inhibition assays) of the first shipment of influenza viruses from Norway for the 2007 08 season showed an unusually large proportion (5/7) of influenza viruses A (H1N1) with high-level resistance to oseltamivir.
High-throughput cell-based and cell-free screening technologies (Xia et al. 2008) that can be applied to screen hundreds of chemicals in dozens of assays for the first time provide data that may be used for the toxicologic evaluation of their potential human health hazard, especially when combined with the knowledge of the chemical structure, metabolism, and disposition.
The aggregates were first placed in N2B27 for 2 days and assayed on the fifth day of culture.
Unless otherwise noted, embryo stages were assayed on the third day of reproduction, 6 d after recovery from L1 arrest, with adults transferred to fresh NGM plates 5 d after feeding to allow progeny to be discarded.
Another SNP (rs1243935) was tagged by the haplotype comprising two rare alleles of tSNPs rs2191249 and rs6504074, but as the assay for the second of these SNPs failed the specific haplotype frequency in cases and controls could not be compared.
The temperature on the skin surface over the vessel called ramus intermedius (diameter about 900 µm) and its surroundings were measured before every assay of the first experimental series (n = 31) using a contact thermometer (TES 1300, Taiwan, accuracy: 0.1°C).
Regarding the antibody titer assay of the first serum samples of the150 clinically diagnosed typhoid fever cases by the four used Widal brands, marked discrepancies were obtained.
This sample was retested using the RPAC assay; results of the second test were negative.
PCR assays of the first 3 CSF samples were negative for JC polyomavirus, herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus, human herpesvirus 6, adenovirus, and Toxoplasma gondii.
The importance of this resource can not be over emphasized: the availability of replicate samples allowed two and three way inter-laboratory comparisons, as well as subsequent technology transfer of the ELISpot assay to the fourth CTC-VIMC core laboratory.
