Isobaric residues and the limits of mass-only identification
Use leucine and isoleucine to understand why equal mass can leave a peptide identity unresolved, even when a measurement is highly precise.

Finding the original paper behind a supplier claim
Trace a scientific statement from a product page to the study that actually produced the evidence, and record where the wording changes.
Read the article →Keeping a reproducible literature search log
Create a search record that another reader can follow: preserve the query, source, date, restrictions, retrieved records and decisions.
Read the article →P-values and common misinterpretations
Read a p-value without turning it into the probability a hypothesis is true, the size of an effect or a guarantee that a finding will repeat.
Read the article →Publication bias in a small research field
Understand how missing studies and selectively reported outcomes can distort the literature, especially when only a few studies are visible.
Read the article →Writing a peptide reagent specification for a study
Turn the study's question into a clear material description, evidence requirements and a record of how suitability will be assessed.
Read the article →Setting evidence requirements for an identity claim
Decide which molecular distinctions matter to a study and what analytical information would actually distinguish the intended peptide from relevant alternatives.
Read the article →What to report about a peptide reagent in a methods section
Write a traceable material description that separates what was supplied, what was measured and what your experiment actually used.
Read the article →Peptides, proteins and amino acids: how the terms relate
Separate free amino acids, residues, peptides and proteins without relying on an artificial universal length cutoff.
Read the article →Endogenous and synthetic peptides explained
Distinguish where a peptide occurs biologically from how a particular laboratory sample was manufactured.
Read the article →Bioactive peptides: what the term does and does not establish
Translate a broad bioactivity label into the actual biological system, measurement and result supporting it.
Read the article →Peptide hormones, neuropeptides and signalling peptides
Understand overlapping functional labels and avoid confusing a signalling peptide with a protein's signal sequence.
