The phrase "alternative to labelling" is correct and usable in written English.
It can be used when discussing different methods or approaches that can replace traditional labelling practices.
Example: "In our research, we explored an alternative to labelling that focuses on user experience rather than strict categorization."
Alternatives: "substitute for labelling" or "replacement for labelling".
Since label-free methods are an attractive alternative to labeling approaches for proteomics researchers seeking for accurate quantitative results we evaluated several open-source analysis tools in terms of performance on two reference data sets, explicitly generated for this purpose.
This study provides an important alternative to label MSCs at optimized low dosages with high efficiency, and the probe may be useful to label other biologically important cells for imaging studies.
Since gadolinium-based MR contrast agents have a high detectability threshold, the use of SPIONs now provides a more promising alternative to label and detect the target cells [2].
To avoid the use of radioisotopes, a fluorescent boron dipyrromethene difluoride cholesterol probe (BODIPY-cholesterol) was used as alternative to label cholesterol [137], [138].
A novel recent alternative to labeling biomolecules with luminescent chelates that has recently emerged is the surface coating of a submicrometer luminescent bead with the biomolecule.
An interesting alternative to labeling an antibody or generic detection reagent with small-molecule lanthanide chelates is, instead, to incorporate the luminescent chelates inside a nanoparticle and coat the surface with the biomolecule.
In conclusion, unlabelled 25(OH)D2, together with sensitive MS, provide a cost-effective and readily available alternative to labelled tracer molecules in populations with expected low or absent plasma 25(OH)D2 but further studies are required to directly compare the metabolism and half-life of 25(OH)D2 and 25(OH)D3 to validate the use of 25(OH)D25
An alternative to labeling the placement of the tie rods is to measure the distance spanned by the tie rod assembly as a whole.
Achieving reliable quantification at reasonable numbers of detected proteins, label-free quantitative proteomics represents a suitable alternative to isotope labelling in addressing a series of biological problems.
This labelling scheme, based on protonated C-glucose and D2O in the growth medium, was previously proposed in solution NMR spectroscopy as an alternative to ILV labelling and in C-detected ssNMR spectroscopy for spectral editing.
