What it does

• Mass for a molarity, the volume for the mass you weighed, and C1V1 with units that convert as you change them
• Salt form, hydrate and purity corrections, with the formula weight from the vial label overriding everything
• A serial-dilution plan with volumes per tube, pipetting flags below 2 µL and the DMSO carried from the stock
• Protein concentration from A280 with ε280 and the molecular weight computed from the sequence, tag on or off
• A buffer's pKa at the working temperature from Goldberg et al. 2002, and a 75-reagent table with hydrate forms
• Stock labels with a QR code drawn on your device, and stocks, plans and recipes kept as objects you can pin, send and study

What it does

• Find and review a canonical protein sequence in UniProt, or paste raw, FASTA, multi-FASTA or GenBank input with the alphabet and ambiguity codes shown
• Reverse complement, translation with the 27 NCBI genetic codes, six frames and open reading frames with every setting on the card
• Protein molecular weight, isoelectric point and ε280, with tags and protease sites found and the numbers before and after cleavage
• Oligo Tm by nearest neighbour under both concentration models, with the Owczarzy 2004 and 2008 corrections and the regime shown
• Primer pair ΔTm and annealing temperature, hairpin and dimer ΔG at 37 °C, and binding sites on a template
• Sequences and constructs kept as objects you can pin, send and study; a protein to the calculators, a peptide to the molecule app, an accession to the protein app

What it does

• qPCR relative expression with reviewed Cq tables, explicit biological samples and calibrators, multiple references, and declared amplification efficiencies
• Plate exports read by recognised layouts at 96 and 384 wells with the header discarded, or a table with units in its headers
• A plate map assigned by keyboard, mouse or touch, filled as a series, saved as a template, or placed from a dilution plan sent by the calculators
• Four-parameter logistic fits in batch, any parameter fixable, unweighted or 1/Y², with unweighted profile extra-sum-of-squares intervals by default and Wald as the named alternative; relative IRLS intervals are unavailable until validated
• Six rules that show a C50 or withhold it with the reason, a relative or absolute C50, Z′ per plate and model comparison by F-test or AICc
• A citable method block, a CSV for GraphPad Prism (XY table) and an R snippet (drc::drm), so the fit can be reproduced elsewhere, with structures beside potencies when a SMILES column is present

What it does

• Paste, FASTA, GenBank and read-only SnapGene .dna files, the pUC19 and pBR322 examples, and public records fetched from NCBI when you ask, up to 50,000 bp
• Circular and linear maps drawn as SVG, operable by keyboard, with the 90 parts of the annotation library found on both strands and across the origin
• Evidence on every feature: identity, coverage, mismatches and gaps, with the word that follows from them
• The sites of 223 commercially available enzymes, with Type IIS cuts, sites across the origin and dam and dcm methylation as you set it
• A diagnostic digest picker that finds the digests telling a correct construct from an empty or reversed one, with a schematic gel and its band table
• Sequencing-primer sites, the plasmid's own weight and the ng, pmol, copies and ligation amounts that follow from it

What it does

• Batch, fed-batch and chemostat runs from versioned presets: E. coli, S. cerevisiae glucose-limited, Pichia on methanol, a chemostat and a custom start
• Dissolved oxygen by its own balance, with C* from the exhaust gas, solved by a stiff solver in a Web Worker
• An oxygen rescue within the agitation, gas-flow and enrichment limits you enter, then a feed cap, with each step as text
• Your measured kLa, your readings at several rpm, or Van 't Riet's correlation with its range stated
• A pump sheet, CSV and chart exports, a printed bench sheet and a method paragraph; a run is a link carrying the preset by id and version and the parameters you changed, never results
• A growth curve reviewed in Assay beside a run, and two measured runs compared on elapsed time from an event you declare, each response on its own axis and never converted

What it does

• Inspect nominal volume, concentration and material origins at each action
• Edit a supported transfer plan while retaining its original
• Check all channels before a transfer is accepted
• Bring a prepared serial-dilution recipe from the calculators
• Save a private protocol and reopen its versioned project file

What it does

• Eight steps from chromatin to haemoglobin, each a real structure from the Protein Data Bank with its primary paper
• A rendered still at once, and a live Mol* 3D view with the same colours and cutaway when you ask for it
• A colour key, labels and plain text for what each step shows
• All eight structures on one nanometre scale
• An address for every step, and the whole tour as text for reading straight through
• Keyboard control and a text description of every picture
