Glycoprotein Intrinsic Tryptophan Fluorescence (ITF) Analysis Service is a highly sensitive, label-free structure analysis service based on the natural fluorescence characteristics of endogenous tryptophan residues of glycoprotein. By monitoring the intensity, wavelength and lifetime changes of tryptophan emission spectrum, the service can reflect the conformational dynamics of glycoproteins in real time under glycosylation modification, ligand binding, amino acid mutations or environmental changes. This service does not require additional fluorescent probes to avoid interference with the native structure of proteins. It is suitable for a variety of scientific research and industrial application scenarios such as glycoprotein conformation research, drug binding analysis, stability evaluation and quality control.
In protein science and glycobiology, glycoproteins have drawn significant attention due to their critical roles in cell signaling, immune regulation, molecular recognition, and disease progression. Glycosylation not only affects the spatial conformation and stability of glycoproteins but also alters their functional properties and interaction modes with ligands. Tryptophan, serving as a natural fluorescence probe, is highly sensitive to changes in its local microenvironment, and its emission characteristics can shift with variations in glycosylation patterns, structural rearrangements, or external conditions. ITF analysis capitalizes on this principle, providing researchers with a high-sensitivity, label-free, real-time approach for monitoring glycoprotein conformations and dynamic changes. With advancements in biopharmaceuticals, structural biology, and precision medicine, ITF analysis has emerged as an important tool for elucidating glycoprotein structure-function relationships, ensuring quality consistency of bioproducts, and streamlining drug development processes.

Analysis Workflow
The general workflow for Glycoprotein Intrinsic Tryptophan Fluorescence (ITF) Analysis Service is as follows:
1. Sample Preparation
Glycoprotein samples undergo buffer exchange, purity verification, and concentration determination to ensure the absence of fluorescent contaminants and compatibility with fluorescence measurements.
2. Fluorescence Spectrum Acquisition
Intrinsic tryptophan fluorescence emission spectra are recorded under specific excitation wavelengths, documenting the emission peak position and intensity.
3. Environmental Sensitivity Assessment
Changes in tryptophan fluorescence peak position and intensity are monitored under varying conditions such as pH, temperature, ionic strength, or ligand addition to evaluate conformational changes and microenvironment effects.
4. Data Analysis and Reporting
Spectral data are processed through baseline correction, normalization, and peak analysis. Changes are interpreted in conjunction with structural or glycosylation data. A comprehensive report is generated, including raw spectra, analysis charts, and professional interpretations.
