Conclusions An enzymatic colorimetry-based DNA microarray assay was successfully established to monitor HBV mutations. Pre-core/core and BCP mutations of HBV genes could be major causes of HBV infection in HBeAg-negative patients and could also be relevant to chronicity and aggravation of hepatitis ...
We evaluated a colorimetric assay for glycosylated hemoglobin to determine the effects of several variables --oxalic acid concentration, extraneous glucose... JC Standefer,RP Eaton - 《Clinical Chemistry》 被引量: 51发表: 1983年 Moisture induced solid phase degradation of l-ascorbic acid part 3, ...
In one such approach, ALP has been detected based on a colorimetric lateral flow assay (LFA) (Yu et al., 2015), which sometime suffers due to the irregularities in porosity causing interruption in flow of target molecule in the paper matrix due to the clogging of pores (Hosseini et al....
Cardiac troponin I (cTnI) is a specific cardiac biomarker for diagnosis of acute myocardial infarction (AMI). A sensitive and simple point-of-care test (POCT) is still required for early detection of AMI. To address this need, we developed a dip strip assay based on sandwich immunoassay ...
Interestingly, compared to the Bromophenol Blue and Alizaringelb dyes’ solution, the NO assay in the m-Cresol Purple dye solution exhibited a noticeable visible color change with a fast response time of ~2 s. Thus, from the above investigation, it can be inferred that the m-Cresol Purple ...

The immunoassay takes ∼30 min from assay to the integrated detection. The conditions for probe antibody microspotting and for the flow-through ELISA analysis in the microfluidic format with integrated detection were defined using antibody solutions with concentrations in the nM–μM range. ...
Dual-mode assayAlkaline phosphatase (ALP) activity plays a crucial role in foods and varies greatly in livestock and dairy products; it is quite difficult to compatibly monitor the different activities in various complicated foods. Herein, we proposed a ratiometric fluorescence and colorimetry dual-...
