Biology
Gene Expression Fold Change Calculator
Quantify how much a gene is up- or down-regulated between two conditions using the 2^(−ΔΔCt) method from qRT-PCR data. Use this when comparing treated vs. control gene expression levels.

Biology
Primer Melting Temperature Calculator
Estimate the melting temperature (Tm) of a PCR primer from its GC content and length using the simplified Wallace-rule approximation. Useful for quickly designing and checking primers before running PCR.
