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...

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 ...

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...

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...

LC-MS proteomic analysis using top-down and bottom-up combined strategies via Filter-Aided Sample Preparation (FASP) was applied to the secretome of mesenchymal stromal cells isolated from the amniotic membrane of human term placenta in the attempt to define the profile of its intact as well as dige...

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...

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...

One of the main goals of shotgun proteomics studies is to identify by mass spectrometry as many proteins as possible, often from low-protein samples, in order to help answer important biological questions. All experimental steps need to be optimized to achieve a thorough proteomic analysis. One of ...

Efficient and reproducible sample preparation is a prerequisite for any robust and sensitive quantitative bottom-up proteomics workflow. Over the past years, several protocols been specifically developed for the preparation of samples, which are limited in quantity. In the present study, we carried ...

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...
