🧬 Protein Synthesis Calculator
Translate mRNA into protein, compute molecular weight, estimate synthesis cost & purity. Perfect for molecular biology and bioprocessing.
Step 1: mRNA / Sequence
mRNA template
Length in nucleotides (multiple of 3 for full CDS). GC content influences translation efficiency. ORFs = potential coding segments.
Step 2: Synthesis Parameters
Synthesis notes
Average amino acid ~110 Da. Error rate adds extra material for truncations. Host factor affects purification cost.

Synthesis cost components
Cost estimation formula
Total cost = (aaCount × costPerAA) × hostFactor × errorRate + purification
aaCount = floor(mRNA length / 3). Host factor adjusts for expression system. Error rate covers failed sequences.
