Protein quantification is fundamental to systems biology and proteomics research. Quantitative analysis of plant proteins is a fundamental step in protein functional determination. We quantify total plant proteins based on the characteristic that the chromogenic groups of proteins or their binding with chromogenic agents produce specific ultraviolet absorption wavelengths. Accurate quantification of plant proteins can further elucidate the mechanisms of action in plant growth, development, metabolism, and disease resistance.
CD BioSciences provides quantitative analysis of total plant proteins based on the physical, chemical, and staining properties of the proteins. Our services help customers gain a deeper understanding of proteins in biological experiments.
Method | Description | Sample Requirements |
UV absorption value at 280 nm | We can quantify proteins containing aromatic amino acids with special UV absorption spectra at 280nm. | The sample is pure and free of impurities. |
Method | Description | Sample Requirements |
BCA | We can quantify most plant proteins using the BCA method based on biuret reaction. This method has a wide application range and low variability. | The protein does not contain chemical modification residues and samples do not contain reducing sugars. |
Method | Description | Sample Requirements |
Bradford or Coomassie leucocyanin | We offer protein quantification methods that are compatible with reducing agents in solution for the quantification of high molecular weight (MW) proteins. | Proteins contain arginine, tryptophan, tyrosine, histidine, and phenylalanine residues. |
Method | Description | Sample Requirements |
Lowry | We provide the Lorry method to represent the total protein concentration by the ratio of sample solution color to protein concentration. It is also suitable for the determination of tyrosine and tryptophan | High protein concentration.
The sample does not contain phenols or citric acid. |
Method | Description | Sample Requirements |
CBQCA | We offer a CBQCA method that is insensitive to certain interfering substances such as lipids. The method can be used to quantify peptides and proteins adsorbed or encapsulated on surfaces. | Protein contains primary amines. |
