The phrase "assay package" is correct and usable in written English.
It can be used in contexts related to scientific testing, particularly in laboratories or research settings where a set of tests or procedures is provided.
Example: "The laboratory received the assay package containing all the necessary reagents and instructions for conducting the tests."
Alternatives: "test kit" or "analysis bundle".
Of compounds tested for cross-reactivity, only two piperazine compounds (other than benzylpiperazine itself) cross-react with the Neogen Benzylpiperazine ELISA (Figure 4B; cross-reactivity data is from both the assay package insert and publication by Swortwood et al. [45]).
Only four compounds (other than MDPV itself) cross-react with the Randox MDPV ELISA (cross-reactivity data is from both the assay package insert and publication by Swortwood et al. [45]).
The 2C and tryptamine series of drugs all possess 2D similarity of less than 0.4 to methcathinone. Figure 3B shows the 2D similarity of compounds with cross-reactivity > 0.8% of methcathinone in the Randox Mephedrone/Methcathinone assay (cross-reactivity data is from both the assay package insert and publication by Swortwood et al. [45]) compared to non-cross-reactive compounds.
Reference intervals may also vary based on assay package inserts, population-specific studies, and/or reference laboratory [ 13].
The manufacturers of commercially marketed steroid hormone immunoassays test a variety of endogenous and synthetic hormones for cross-reactivity and report this data in the assay package insert, typically as percent cross-reactivity or sometimes qualitatively (e.g., using a descriptor such as "cross-reacts").
Protein concentration was determined using the Bio-Rad DC Protein Assay Reagent Package (Bio-Rad Laboratories, Inc., Hercules, CA, Cat. 500-0116). 500-0116
Cystatin C was measured in a batch in the University of Colorado Hospital clinical laboratory using the commercially available Dade-Behring assay following package insert instructions on a BNII instrument.
Based on a locus-specific primer extension reaction, a locus-specific PCR reaction was designed using the MassARRAY Assay Design software package (v3.1).
Recovery of Erv25p (a constituent of COPII vesicles) in the vesicle fraction in the defined system and absent from control membranes demonstrates the efficacy of the assay (Average packaging efficiency, 8.9%. Figure S2A).
Based on the investigation performed by various laboratories under the International Collaborative Study, this reference serum had the overall geometric mean titer (GMT) of 183 by HI and 516 by microNT assays (NIBSC package insert).
Using a semi-quantitative RT-PCR approach on heterologous non-viral vector RNAs in an in vivo packaging assay, this study demonstrates that the principal packaging determinants of FIV reside within the first 150 bp of 5′ UTR and 100 bp of gag (the two core regions) and not the viral 5′ LTR.
