Protein identification and analysis of single proteins or protein mixtures, as well as protein sequence analysis of single proteins, are frequently encountered problems in plant biology research. Protein identification is achieved by obtaining sequence information of protein sequences based on mass spectrometry and protein mass spectrometry identification by mass spectrometry. Common analyses include molecular weight determination by mass spectrometry, N-terminal and C-terminal sequencing of proteins, protein sequence analysis, and post-translational modification site analysis, etc. Lifeasible uses ultra-high resolution mass spectrometry-based on Q Exactive mass spectrometer, LTQ Orbitrap Elite mass spectrometer, combined with Nano-LC liquid chromatography technology to provide efficient and accurate protein identification services for proteins in plant protein extracts, SDS-PAGE protein strips, 2D protein dots, pull-down, and co-IP samples.

What We Offer

• Protein mass spectrometry identification of purified plant proteins.
• Identification of protein gel dots, protein gel strips by mass spectrometry, identification of protein silver-stained glue mass spectra, identification of glue dots/strips samples stained with fluorescence/Zn/Cu²⁺ types.
• Protein identification and analysis of protein samples from simple mixture samples by pull-down protein spectrometry identification, IP-MS reciprocal protein identification for IP protein reciprocal, co-IP mass spectrometry to verify reciprocal proteins, immunoprecipitation combined with mass spectrometry validation, etc.
• Protein identification by protein spectrometry of unknown proteins in complex samples, even very low concentration protein samples may be identified by protein profiling.

Service Flow

Sample Requirement

• Samples of one or more proteins, such as gel strips, solution or solid samples, pull-down, or co-IP samples.

*For plant protein samples identified by mass spectrometry, gloves, and head coverings should be worn during sample preparation to avoid contamination of the sample by your own keratin.

*The experimental samples will not be returned, please back them up by yourself.

*Other important notes can be obtained by contacting our staff directly.
