Construct a standard curve for most protein assay methods as fast as you can pipette. The BCA™ Protein Assay produces a linear response curve (r2> 0.95) and is available in two formulations based upon the dynamic range needed to detect the protein concentration of an unknown sample.
Hello, we provide concise yet detailed articles on "Protein Choices: Bca Protein Assay Standard Curve" topic. The information here is sourced well and enriched with great visual photo and video illustrations.
I made curve for standard protein 10-60 . The relationship between concentration and absorbance is not linear in BCA/ELISA assays. You can use Excel Trendlines to fit Polynomial relationships.
We did the Pierce BCA assay and ran the standard curve (and were able to estimate protein concentrations in our samples). We had excess standards so we decided to save them and are currently stored in -80 freezer. It just seemed kinda wasteful to do the assay every time; in terms of...

The standard BCA™ Protein Assay (Figure 3) detects protein concentrations from 20 to 2,000 µg/ml and is provided Figure 3. Color response curves obtained with the BCA™ Protein Assay using bovine serum albumin (BSA) and bovine gamma globulin (BGG).
BCA Protein Assay Kits are limited for research purposes only. Note: If a curve-fitting algorithm associated with the microplate reader is used for preparing the standard curve, a four-parameter (quadratic) or best-fit curve will provide the most accurate results.
The Pierce BCA Protein Assay is one of the most commonly used protein quantitation assays, so we have determined the compatibility of this assay BSA standard curves (between 0-1,000µg/ml) were prepared in either water (control) or various dilutions of the following lysis buffers or resuspended...
Bicinchoninic acid (BCA) assay or Smith assay is a copper-based colorimetric assay for total protein quantification. BCA rely on the formation of a Cu2 +-protein complex in a basic environment, followed by reduction of the Cu2 + to Cu+ (Smith et al., 1985).
Use the standard curve to determine the protein concentration of each unknown sample. Note: If using curve-fitting algorithms associated with a microplate reader, a For further information, visit the ThermoFisher Scientific Pierce BCA Protein Assay Kit: https...
Typical protein assays are used to determine protein concentration by comparing sample assay response to that of a standard whose concentration is known. Pre-Diluted Standard Curve Range: 125-2,000 µg/ml for BCA, Coomassie and Bradford Assays.
BCA Protein Assay (Pierce, Illinois): the kit includes BCA Reagents A and B, and BSA protein standard (2 mg/ml). The BCA Protein Assay is described by two different procedures: one for microplates and the other for cuvettes, both within a working range of...
