The phrase "a assay" is not correct in written English.
The correct form is "an assay" because "assay" begins with a vowel sound.
Example: "The laboratory conducted an assay to determine the composition of the sample."
Alternatives: "a test" or "an analysis".
SAA levels were measured using a double sandwich ELISA (Phase Serum Amyloid A Assay, Tridelta Ltd., Ireland).
a Assay of expression and solubility of IFN-CSP in recombinant E. coli.
Fourier Transform Infrared (FTIR) spectroscopy and the azure A assay were used to evaluate interactions between dendrimers and enoxaparin.
The FTIR data and azure A assay revealed ionic interactions between the amino groups of cationic dendrimers and the carboxylic and sulfate groups of enoxaparin.
Three bioassays were conducted to compare the virulence of the Bb-AaIT and WT strains as follows: a assay 1, the second-instar larvae of Aedes albopictus infection through conidia ingestion.
Still existing difficulties with Lp(a) laboratory measurement require a practical approach to establish the indication for LA considering the 60 mg/dl threshold of German guidelines with selecting an Lp(a) assay which has been calibrated for mass.
Additionally, due to the characteristics of erythropoiesis, the PIGRET assay can potentially detect increases in Pig-a mutant frequency (MF) sooner after exposure compared with a Pig-a assay targeting total RBCs (RBC Pig-a assay).
The TaqMan gene expression assay ID for different targets were: GAPDH (Assay ID: Hs99999905_ml and VEGF-A (Assay ID: Hs00173626_ml.
Follistatin and activin levels were assayed by using commercial ELISA kits (Human Follistatin Immunoassay, AN'ALYZA and Activin-A ASSAY, Oxford Bio-Innovation, respectively).
A cocktail of MAP assays for the common 15/18 bp deletions, together with a Bi-PAP-A assay for the common L858R mutation, could detect about 70 80% of EGFR mutations constituting about 10% of total lung cancers [10], [36].
This paper describes four assays that detect somatic gene mutations in humans: the hypoxanthine-guanine phosphoribosyl transferase assay, the glycophorin A assay, the HLA-A assay, and the sickle cell hemoglobin assay.
