Mass, sequence and primer calculators
Enter monosaccharide counts and get exact masses for glycans and glycopeptides, per-methylated products and ESI adduct m/z.
Cleaves a protein sequence with the same rules ExPASy uses and reports every peptide’s mass and [M+H]+, with cysteine modification.
Theoretical m/z for the a/b/c and x/y/z series with 1+ to 3+ charges, internal losses and global modification rules.
Grand average of hydropathy from the Kyte & Doolittle scale, batch FASTA input and a per-residue window profile.
Nearest-neighbour Tm corrected for salt and primer concentration, with GC% and hairpin / self-dimer checks.
Gel & solution prep
Recipes and dilutions at the bench
C1V1=C2V2 dilutions with any term missing, molarity-to-mass weighing, and buffer pH recipes for the three usual prep jobs.
Volumes for separating and stacking gels from the number of slabs and the target acrylamide percentage, APS and TEMED included.
Data processing & statistics
Table cleaning, tests and dimension reduction
Plotting & visualization
Figures, palettes and set relations
Plot an expression immediately: Cartesian and polar curves, inequality regions and parameter sliders, export when you like the view.
Paste up to four lists to get 2/3/4-set diagrams, area-proportional or not, with element lookup and SVG / PNG export.
Upload a figure and see it through protanopia, deuteranopia and tritanopia, in greyscale, with a verdict on the palette.
Text & writing
Citations, diff and regex
Fill the fields once and get the reference in APA 7, MLA 9, Chicago, IEEE and GB/T 7714 styles.
Live match highlighting with every capture group listed, a replacement preview and a cheat sheet of common patterns.
Side-by-side line comparison with word-level highlights, accept or reject each change on its own, then export the merged result.
