  • Product overview

    BCA Protein Assay Kit ab102536 provides a simple, rapid, detergent tolerant (up to 5%) procedure for determining the concentration of proteins in solution.

    The method utilizes a copper (Cu2+) salt which can be reduced to the cuprous state by protein(s).

    The generated Cu2+ ion forms an intensely colored complex with the bicinchoninic acid reagent with a very strong absorbance band centered at 562 nm.

    The intensity of the blue complex is proportional to the amount of protein in the sample. The BCA Protein Assay is suitable for measuring protein concentration in the range of 0.5-30 µg protein (0.01-0.6 mg/ml).

  • Notes

    This kit was previously called BCA Protein Quantification Kit.



  • Standard Curve at 60°C.
  • Standard Curve at 37°C.

Thank you for contacting us.

I have attached a graph of absorbance values measured at various wavelengths of light for various concentrations of BSA. The data demonstrates that the maximum absorbance is at 562nm but there is little loss of a...

It all depends on the concentration of EDTA and Citrate. For instance, EDTA<10mM and sodium citrate <200mM can be used with a standard BCA assay. Please be aware that the BCA assay is based on Copper ion chemistry, therefore it is not advised to ...

I can confirm that both BCA and Bradford protein quantification kits can be used for human serum and plasma samples. The main difference between the two kits is that the BCA assay uses a Copper ion based chemistry whereas the Bradford assay uses a Coom...

Vielen Dank für Ihre Anfrage.

Ich kann bestätigen, dass die meisten Methoden zur Proteinbestimmung nicht funktionieren wenn Detergenzien enthalten sind.

Die beste und robusteste Methode ist deshalb der BCA Protein Assay. D...

That is no problem at all. I hope it was of some help to you. If you could let me know the target you are looking at I can have a look at the way we prepare lysates, if we have an antibody directed towards it?

Otherwise, I wish you all the bes...

Thank you for your email and sorry for my late reply.

I think if an expert in the field has suggested this method has worked for his group it may well be worth trying. What you could always do is try both methods of lysis and probe the samples...
