Title: Innovations by Inventor Ning Liu

Introduction

Ning Liu is a prominent inventor based in Fremont, CA (US). She has made significant contributions to the field of protein quantification and normalization. With a total of 5 patents, her work has advanced the methodologies used in protein analysis.

Latest Patents

One of her latest patents focuses on stain-free protein quantification and normalization. This invention discloses methods that utilize haloalkylated tryptophan fluorescence for protein quantification. The technique allows for the analysis of complex protein samples containing 1,000 or more distinct proteins from diverse sources. By treating these samples with halo-substituted organic compounds, fluorescent products are formed, which can be detected and quantified using ultraviolet light. This method provides valid comparative values for total protein content, despite variations in tryptophan levels among different proteins. Additionally, her patent addresses normalization of protein samples to correct for inconsistencies in sample dilution and loading.

Another significant patent by Liu involves immunoblotting systems and methods. This invention describes a method where an antibody solution is applied to a membrane containing an optically detectable protein and a target protein. The application of the antibody solution is guided by signals emitted from the optically detectable protein, allowing for effective detection of the target protein.
