Calculate the concentration of protein solutions using an absorbance reading at 280 nm. Mar 21, 2026 · Convert A280 absorbance into protein concentration in mg/mL or uM using epsilon, E1%, or a quick estimate. The concentration of any protein can be calculated by inputting the amino acid sequence or the UniProt ID. Designed for busy biochemistry, molecular biology and cell culture labs. This is used to convert the weight (weight concentration) into the molar quantity (molar concentration) for proteins, and vice versa. Free protein concentration calculator to convert mg/mL to µM and molarity. Select the protein type, enter the absorbance, dilution factor and pathlength, or enter the amino acid sequence or UniProt ID. This calculator is used to determine the concentration of protein solutions using an absorbance reading at 280 nm. This calculator will determine the protein concentration of your stock or diluted sample. It then applies the selected coefficient method and finally adjusts for any dilution so the answer reflects the original sample.

Jun 15, 2026 · Calculate protein concentration instantly using A280, standard curve, or Warburg-Christian methods. This is used to convert the weight (weight concentration) into the molar quantity (molar concentration) for proteins, and vice versa. The protein concentration calculator helps you determine a stock's protein concentration or dilution from spectroscopic absorbance measurement. What is the Protein Concentration Calculator? Definition: This calculator computes the concentration of a protein sample based on its absorbance at a specific wavelength (${\lambda }_{\text{max}}$), using the Beer-Lambert Law modified for protein properties. We would like to show you a description here but the site won’t allow us. Use our Protein Concentration Calculator to compute protein concentration from A280 absorbance (Beer–Lambert), linear standard curves (Bradford/BCA/Lowry), or dilution calculations (C1V1=C2V2). . Mar 21, 2026 · The calculator first finds the absorbance that actually came from the protein sample by subtracting the blank from the sample reading. Dec 14, 2025 · This calculator estimates protein concentration from UV spectrophotometry data. 86scfa, p0qm9ava, 2y, 3osx, ti3, qdp, sht, eci, im, 2fdwvw,
