protein isoforms, each of which may undergo cleavage, folding and post-translational modificatio
resulting in over a million proteoforms. Hence, the impact of the proteome reflects a variety of biological
functions that are difficult to infer from genomic or transcriptomic data alone.

Choosing the right proteomics approach
Selecting the appropriate proteomics method is crucial to unraveling the secrets of human disease. The
choice of method can impact data quality and coverage, and it can enhance discovery power.
I’m a proteomics researcher looking to resolve isoform
differences. I need an affordable solution that can
differentiate isomers.
Next-generation protein sequencing approaches can
accurately differentiate between isomers and identify
protein variants and modifications at the amino acid level.

I’m new to proteomics but know a lot about genomes, and
I also know that transcription does not equal translation. I
need an easy-to-use solution that can help me correlate
gene sequence to protein sequence.

I perform a lot of immunoassays, but these methods
require highly specific antibodies and they don’t provide
me with information about protein sequence or variants.
Is there a more specific method I could use that does not

Next-generation protein sequencing enables deeper
discoveries through the interrogation of amino acid residues
without the need for highly specific antibodies to perform
the analysis.
