For FACS analysis of EdU, single sorted cells were fixed with 4% PFA, stained using the Click-It assay for Alexa-647 and re-analyzed by FACS (MoFlo, BD Bioscience).
The RNA concentration was determined using a Quant-iT Assay Kit for RNA quantification (Invitrogen) and was verified by electrophoresis.
Prepared libraries have undergone a quality control using an Agilent 2100 Bioanalyzer: DNA 1000 Labchip, Quant-iT dSDNA HS Assay for quantification and Quant-iT RNA Assay and Quant-iT Protein Assay for percentage contamination check, using an Invitrogen Qubit® Fluorometer.
Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-nucleotide polymorphism-identification technology (SNP-IT) assay were performed for genotyping of HER-2 polymorphisms.
To evaluate the effect of age upon QuantiFERON-TB Gold-In-Tube (QFT-IT) assay outcome among children examined for latent tuberculosis infection (LTBI).
It is noteworthy that comet assay is more sensitive than DNA ladder assay in detecting DNA damage and distinguishes apoptosis from necrosis making it a reliable assay for detection of apoptotic cell death [ 38].
Culture fluid was clarified by low-speed centrifugation, following which it was assayed for MMP-1 as indicated below.
The supernatant was removed and stored at −80 °C until it was assayed for cytokines (human and murine TNF, and murine IL-1 β, IL-4, IL-10, IFN γ and transforming growth factor- β enzyme-linked immunosorbent assay (ELISA) kits (Affymetrix, San Diego, CA, USA) or used in blotting and in neutrophil assays.
For a fee, it assays & refines these metals for private concerns.
It is difficult to assay for antibody cross-reactivity in adults, since it is impossible to trace the exact strains an individual was exposed to during his life.
Using enzymes, it is possible to assay for a specific substance from specimens of serum or urine without the need for isolation of the substance which simplifies the process and shortens the assay time.
