And George M. Whitesides, a Harvard chemist, got intrigued by the same challenge and began work on a revolutionary variant: skip all the plastic and let the fluids instead be wicked through paper the size of a postage stamp infused with color-changing reagents.
The presence of ruminant DNA in the reagents could not be controlled, and has the potential of changing between reagent lots.
We adapted the MBTH method for rapid detection of sugars by changing the amount of reagent added and reducing the incubation temperature from 80°C to 60°C.
High catalytic activities and efficient comonomer incorporations can be easily obtained by changing monomer masking reagents and polymerization conditions in the presence of diethylaluminium chloride as a cocatalyst.
The degradation rate of HA hydrogels were thought to be controlled by changing the crosslinking reagents and the functional group of HA derivatives.
However, these epigenetic patterns can be altered under certain environmental conditions (inflammation, viral infections and chemical reagents), changing chromatin structure and modifying gene transcription, contributing to cell plasticity and, ultimately, determining the strength of post-transplant immune responses (Fig. 1B).
Changing the proportions of reagents leads either to γ- or layered structures of MnO2.
By changing the secondary reagent 1-ethyl-3- 3-dimethylaminopropyll) carbodiimide instead of sodium cyanoborohydride), 4-APEBA is also applicable to the selective derivatization of carboxylic acids.
After PCR optimization, including gradient PCR for testing annealing temperature and changing the proportion of reagents, 17 (25.8%) of these loci generated stable and clear bands with independent annealing temperatures (Table 2).
It can complete the screening and confirmation of an HIV infection within 1 to 2 hours and is easily adapted to detect different targets by changing the NA amplification reagents with the appropriate set of primers and the LF strips with matching capture zones.
