NH DyeAGNOSTICS (NHD) sees a steadily increasing demand on its Protein Services. Beside the identification of potential biomarkers, there is increasing demand on Host Cell Protein analysis as well as the identification of differentially modificated proteins (e.g. Glycosylation).
A key role is NHDs long-term experience in sample preparation especially when it comes to more challenging samples. In addition our well focussed analysis strategies ensure rapid and most valuable results.

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.
