This study provided a fast, label-free, and low-cost platform for the comprehensive assessment of OCP.
In addition, the modulation of TPM dye/G-quadruplex complex fluorescence by Ag+ and Cys could be used to develop a simple, fast, label-free and highly specific homogenous sensing methods for Ag+ and Cys.
Breath analysis represents a new diagnostic technique that is without risk for the patient; therefore, it is very important to develop microanalytical systems which can offer a fast, label-free, low cost, no damage and on-site monitoring biomarkers of lung cancer in exhaled air.
Panning around is super fast, labels appear quickly.
Since the calcium binding sites in C2A may interfere with copper binding we sought a high affinity, fast labelling chelator.
The strengths of this derivatization strategy involve fast labeling (15 s), low chemical background and general access to most carboxylic analytes.
Thus, a strong need still remains for an efficient labeling method that can combine both a fast labeling rate (within tens of seconds) and high specificity with real-time detection and high-contrast imaging.
Both chelating agents exhibited strong selective coordination of 89Zr and 68Ga and offered a very fast labelling kinetic at room temperature as compared to DFO and DOTA/NOTA analogs.
There seems to be a kind of an optimum amount of 4.8% DOTA for a very fast labeling and at the same time 11% DOTA is too much to efficiently coordinate gallium into the chelator and 1.6% DOTA is insufficient to quantitatively bind gallium, but after 25 min, no differences between the various DOTA amounts were evident.
Eventually, surface plasmon resonance (SPR) has attracted attention as a fast label-free screening method for the detection of food contaminants, in particular, mycotoxins [ 28– 34].
In this study, a new pair of fast labeling SNAP and CLIP-tag variants, termed SNAPf and CLIPf, were utilized as fusion partners.
