About GST-Fusion Protein Net Charge vs pH Calculator
Calculate the net charge at a chosen pH of a gst-fusion protein from its amino-acid sequence. Useful for ion-exchange and solubility decisions. 100% in-browser — your sequence is never uploaded. The calculation uses q(pH) via Henderson–Hasselbalch. The stakes: The extinction coefficient sets every A280 concentration you report; the pI decides your ion-exchange and solubility strategy. These numbers underpin purification and quantitation. GST-Fusion Protein: Useful for ion-exchange and solubility decisions. Watch out for: assuming pI from sequence equals experimental pI exactly; ignoring post-translational modifications; forgetting cystine (disulfide) contributions to ε280. Because the calculation happens entirely client-side, you can use it offline and with confidential data, then cite the stable URL in your methods or teaching notes.
