Lymnaea shell proteomics


The calcifying matrix proteins embedded within the shell biomineral structure is a mixture of proteins, glycoproteins, and polysaccharides that are involved in the shell formation processes. Here with develop bottom-up shotgun proteomic investigation of these proteins, thanks to specific transcriptomic data generated from the calcifying mantle of adult Lymnaea.

Sample Processing Protocol

The acid-soluble and the acid-insoluble matrix proteins were extracted from adult shells, then reduced, alkyled and digested with trysin prior to nanoLC-ESI MS/MS analysis on a QSTAR (Sciex) coupled to a Dionex U3000 HPLC.

Data Processing Protocol

MFG file was then generated from wiff raw data using Anatyst 1.1 software, then data were analyzed using Mascot serach engine 2.4, against an in-house transcriptomic database.
