ProteomicsFormaldehyde derivatization, a Side Reaction During Filter-Aided Sample Preparation
The filter-aided sample preparation (FASP) method has been commonly used for proteomic sample preparation due to its high efficiency and convenience. Herein, we report an overlooked side reaction during FASP method, resulting in a mass increment of 12 Da. We confirmed that the side reaction is cause...

ProteomicsUltrasonic-based filter aided sample preparation as the general method to sample preparation in proteomics
In this work, we propose a new high-throughput ultrafast method for large scale proteomics approaches by speeding the classic filter aided sample preparation protocol, FASP. The new US-FASP method matches the analytical minimalism roles as time, cost, sample requirement, reagent consumption, energy ...

ProteomicsFilter aided, single tip (FAST) method for high throughput, ultrasensitive proteomics sample preparation reveals proteome asymmetry in Xenopus embryos
We report a filter aided, single tip (FAST) method for ultrasensitive proteomic sample preparation. To minimize sample loss and contamination, the method reduces the surface area of the filter to ~0.1 mm2, the total volume of reagents to < 10 μL, and the number of sample transfer steps to two. 25,88...

ProteomicsValidation of filter aided sample preparation (FASP) approach for quantitative plant shotgun proteomics
Gel-free LC-based shotgun proteomics represents the current gold standard of proteome analysis due to its outstanding throughput, analytical resolution and reproducibility. Thereby, the efficiency of sample preparation, i.e., protein isolation, solubilization and proteolysis, directly affects the co...

ProteomicsSample preparation procedure for mass spectrometric analysis of plant histones
The protocol for preparing samples of plant histones prior to LC-MS/MS analysis was established, using a filter-aided sample preparation (FASP) technique to remove natural contaminants and chemical additives incompatible with MS-based procedures. The protocol consists of nuclei isolation, histone ex...

ProteomicsLarge-scale filter-aided sample preparation method for the analysis of the ubiquitinome
Protein ubiquitination regulates key cellular functions including protein homeostasis and signal transduction. The digestion of ubiquitinated proteins with trypsin yields a glycine-glycine remnant bound to the modified lysine residue (K-ε-GG) that can be recognized by specific antibodies for immunoa...

ProteomicsSensitivity and protein digestion course of proteomic Filter Aided Sample Preparation
1. Sensitivity of FASP was tested using SDS lysates from HeLa cells and mouse brain. Peptides were analyzed using a QExactive HF-X instrument. We found that FASP allows effective processing samples at the low and sub-microgram range. 2. Whole cell lysates of Hela cells were processed with FASP using...
