Protein Synthesis Calculator — mRNA translation & protein cost

🧬 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.

Typical start: AUG (Met). Stop: UAA/UAG/UGA. CAI >0.8 indicates good expression in chosen host.

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.
