Over decades, Western blotting is a method to detect a target protein in a complex sample. The technique includes protein separation, transfer to a membrane and several washing and antibody incubation steps.
Reliable comparison of detected target signal intensities between different samples is still a problem. It requires an appropriate way of normalization to assure that the reported fold changes of the target protein are not an artifact of a reference signal and/ or experimental errors.
Smart Protein Layers (SPL) is a add-on kit for the detection of sample proteins present on the blot at the same time the target is immuodetected. It is based on two components: i) fluorescent SPL Labels, bound to the sample protein prior separation, for the visualization of all proteins present on the blot at this time ii) bi-fluorescent SPL Standards to monitor labeling efficiency and to provide additional information about the sample and to enable automated data evaluation.
With SPL the determined expression of a specific target protein can be normalized to its corresponding sample, providing a reliable and precise tool for the comparison of fold changes between different samples.
