2-8°C

Quality Level

Application

El reactivo de Bradford se ha utilizado para determinar la concentración total de proteínas.

Features and Benefits

  • El reactivo está listo para usar. No se requiere mezcla ni dilución.
  • La aparición del color es rápida. Bastan 5 minutos de incubación y la muestra puede leerse a 595 nm.
  • Los azúcares reductores y las sustancias reductoras junto con los tioles no interfieren con este reactivo.
  • El reactivo es adecuado para microanálisis (1 - 10 μg/ml) y análisis convencionales (50-1400 μg/ml).
  • Puede utilizarse en análisis de placas de micropocillos.
  • Análisis barato.

General description

El análisis de Bradford consiste en añadir azul brillante de Coomassie G-250 a la disolución proteica. El colorante azul Coomassie se asocia con los aminoácidos básicos y aromáticos, causando de este modo un viraje en la absorbancia durante la determinación de proteínas.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. Will the buffer or solution my protein is in interfere with Product B6916, Bradford Reagent?

    A compatibility chart is listed in the bulletin. If your substance is not listed, then we recommend testing this by diluting the standard protein samples in the same buffer as the unknown samples.

  3. What is the useful concentration range that can be measured by Product B6916, Bradford Reagent?

    The Bradford Reagent requires no dilution and is suitable for micro, multiwell plate, and standard (cuvet) assays. The linear concentration range is 0.1-1.4 mg/mL of protein, using BSA (bovine serum albumin) as the standard protein.

  4. When using Product B6916, Bradford Reagent, how soon after my color development do I need to read my assay?

    he protein-dye complex is stable up to 60 minutes. The absorbency of the samples must be recorded before the 60 minute time limit and within 10 minutes of each other.

  5. When using Product B6916, Bradford Reagent, what can I do if I have a very dilute sample in a large volume?

    The micro assay using this same reagent may be an option for you. The micro assay is used when a large volume (at least 1 mL) of a dilute sample is available for testing. The linear concentration range of this assay is lower than the standard or multiwell plate assays, (1-10 μg of total protein in 1 mL).

  6. Is the BSA standard supplied with Product B6916, Bradford Reagent?

    No, we do not supply the BSA standard with this reagent. We recommend using one of the following products: Protein Standard (BSA) Solution, (2 mg/mL), Product No. P0834 or Protein Standard (BSA) Solution, (1 mg/mL), Product No. P0914, if lower concentrations of protein are to be measured.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  8. How do I find price and availability?
