BioChemCalc（BCC） is a web-based tool for essential calculations and checks in everyday life science research． BCC Magazine shares practical uses of BCC and useful research insights to support open and independent science．
Compare Gaussian and generalized Gaussian functions with interactive sliders for amplitude, center, scale, and shape exponent. Explore peak width, tails, FWHM, and examples from biology and microscopy.
Explore Logistic and Burr XII curves with live sliders, mathematical limits, and synthetic examples from pharmacology, cell survival, and protein degradation.
Learn the difference between RPM and RCF (×g), why rotor radius matters, how to convert centrifuge speed correctly, and why reporting RPM alone can reduce experimental reproducibility.
Multiple PCR bands do not always mean failed amplification. Learn how primer specificity, annealing temperature, primer dimers, reaction conditions, contamination, genomic DNA, and alternative splicing can produce unexpected bands, and how to distinguish technical problems from real biology.
Learn how PCR primer design, agarose gel electrophoresis, DNA ladders, and semi-log calibration can be used to estimate DNA fragment size and support genotyping, SNP detection, sequencing, and cloning.
A practical guide to free BioChemCalc assistant tools for LC and LC/MS workflows，including solvent mass-volume conversion，pressure conversion，column internal volume，and linear velocity calculation.
Learn how to calculate molarity from mass, volume, and molecular weight with simple step-by-step examples.
A basic workflow for analyzing RT-qPCR data by combining statistical testing, heatmap visualization, and hierarchical clustering analysis.
