Insect Cell Glycosylation Patterns Analysis Service

Insect cell glycosylation patterns refer to the process in insect cell expression systems where proteins undergo post-translational modifications with specific glycans attached through enzymatic reactions. This modification not only affects the spatial conformation and stability of proteins but also determines their roles in secretion, activity regulation, and molecular interactions. Due to the critical role of glycosylation in protein therapeutics and vaccine development, the study and detection of insect cell glycosylation patterns have attracted increasing attention.

In the production of recombinant protein drugs and vaccines, accurate analysis of glycosylation patterns is essential for ensuring product quality and consistency. Through systematic analysis of glycosylation patterns, researchers can gain a comprehensive view of glycosylation in insect cell products, evaluate their immunogenicity, stability, and long-term controllability.

Services at MtoZ Biolabs

MtoZ Biolabs integrates multiple analytical technologies to ensure comprehensive and accurate detection of insect cell glycosylation patterns. Our insect cell glycosylation patterns analysis service covers the following core technologies:

1. Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS)

LC-MS/MS is one of the mainstream technologies in glycosylation research. By separating glycopeptides or glycans in samples with high-resolution liquid chromatography and detecting them with high-resolution mass spectrometry, it can simultaneously identify glycosylation sites and confirm glycan structures. This method is suitable for complex mixed samples and can reveal glycan diversity and relative abundance distribution.

2. Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS)  

MALDI-TOF MS is a high-throughput detection method commonly used for glycan profiling and overall pattern analysis. By detecting released glycans, it can quickly obtain global glycosylation information of samples. This method is simple and efficient, especially suitable for preliminary screening and comparative studies of multiple batches.

3. High-Performance Liquid Chromatography (HPLC/UPLC-FLR)

HPLC or UPLC-FLR combined with fluorescent labeling plays an important role in glycan separation and quantification. Through fluorescent derivatization of glycans, clear distribution profiles can be obtained at high sensitivity. This method is often used for quality control and is suitable for studies and production scenarios requiring strict evaluation of glycan proportions.

4. Capillary Electrophoresis (CE)

CE shows excellent resolution in glycan separation, especially for structurally similar glycan isomers. This technology complements chromatography and mass spectrometry and has important applications in the detailed study of complex glycans.

5. Enrichment and Derivatization Techniques

• Lectin affinity enrichment: Enhances the detection sensitivity of specific glycotypes through selective binding.
• Chemical derivatization (such as permethylation and reductive amination): Increases glycan signal intensity in mass spectrometry and optimizes structural resolution.
