Biology
PCR Primer Tm Calculator
Calculates the melting temperature (Tm) of short PCR primers using the Wallace rule base-counting method. Use it when designing primers under 20 bases or for a quick sanity check before ordering oligos.

Biology
Mitotic Index Calculator
Compute the mitotic index — the fraction of cells actively dividing — from the count of mitotic cells and the total cell count, expressed as a percentage. Standard cytology metric for assessing tissue proliferation in tumour grading, embryo development studies, and cell-culture monitoring.
