Shape-Enhanced Open-Channel Hydrodynamic Chromatography.
Biagioni V, Cerbelli S, Desmet G. Biagioni V, et al. Anal Chem. 2022 Nov 22;94(46):15980-15986. doi: 10.1021/acs.analchem.2c02766. Epub 2022 Nov 12. Anal Chem. 2022. PMID: 36370088
Hydrodynamic chromatography (HDC) is a well-established analytical separation method for the size separation of nano- and microparticles and large molecular weight solutes such as synthetic polymers and proteins. We report on a theoretical study showing that the sep …

Gel-filtration chromatography.
Hagel L. Hagel L. Curr Protoc Protein Sci. 2001 May;Chapter 8:Unit8.3. doi: 10.1002/0471140864.ps0803s14. Curr Protoc Protein Sci. 2001. PMID: 18429205
Three basic protocols are provided in this unit, corresponding to the major applications of gel filtration. One method describes desalting or group separation, in which the target protein and contaminating solutes differ substantially in molecular size. Another is u …

Gel-filtration chromatography.
Hagel L. Hagel L. Curr Protoc Mol Biol. 2001 May;Chapter 10:Unit 10.9. doi: 10.1002/0471142727.mb1009s44. Curr Protoc Mol Biol. 2001. PMID: 18265066
Gel filtration (GF) chromatography separates proteins solely on the basis of molecular size. Separation is achieved using a porous matrix to which the molecules, for steric reasons, have different degrees of access--i.e., smaller molecules have greater access and larger mo …

Kendrick mass defect analysis - a tool for high-resolution Orbitrap mass spectrometry of native lignin.
Pikovskoi II, Kosyakov DS. Pikovskoi II, et al. Anal Bioanal Chem. 2023 Jul;415(17):3525-3534. doi: 10.1007/s00216-023-04742-3. Epub 2023 May 24. Anal Bioanal Chem. 2023. PMID: 37222795
Being a complex mixture of oligomeric molecules with an irregular structure, natural lignin is an extremely difficult object to study. Its molecular level characterization requires advanced analytical techniques among which atmospheric pressure photoionization Orbitrap …

Mass and molecular weight of isolated nuclear rings.
Aréchaga J, Diaz J, Silió M, Bahr GF. Aréchaga J, et al. Biol Cell. 1990;68(1):13-20. doi: 10.1111/j.1768-322x.1990.tb00888.x. Biol Cell. 1990. PMID: 2317594
In previous publications we have dealt with their morphology, relationships with the nuclear membranes, chromatin fibers and cytoskeletal filaments; and more recently, with their measurements at high electron microscope resolution. In this article we have calculated the mass …

High-resolution tandem mass spectrometry of large biomolecules.
Loo JA, Quinn JP, Ryu SI, Henry KD, Senko MW, McLafferty FW. Loo JA, et al. Proc Natl Acad Sci U S A. 1992 Jan 1;89(1):286-9. doi: 10.1073/pnas.89.1.286. Proc Natl Acad Sci U S A. 1992. PMID: 1309610 Free PMC article.
Unit-resolution mass spectra have been obtained for peptides as large as 17 kDa, providing information on impurities and adduct ions, as well as accurate molecular weight values. Electrospray ionization produces many multiply-charged species of the sam …

Zymography of metalloproteinases.
Troeberg L, Nagase H. Troeberg L, et al. Curr Protoc Protein Sci. 2004 Nov;Chapter 21:21.15.1-21.15.12. doi: 10.1002/0471140864.ps2115s33. Curr Protoc Protein Sci. 2004. PMID: 18429257
The technique is particularly useful for analyzing the peptidase composition of complex biological samples because visualization depends directly on proteolytic activity. This unit presents a representative zymography protocol for the study of matrix metallopeptidases (MMP …

Mass determination of phosphoramidites.
Harusawa S, Fujitake M, Kurihara T, Zhao ZY, Lilley DM. Harusawa S, et al. Curr Protoc Nucleic Acid Chem. 2006 Oct;Chapter 10:Unit 10.11. doi: 10.1002/0471142700.nc1011s26. Curr Protoc Nucleic Acid Chem. 2006. PMID: 18428946
Nucleoside phosphoramidites are the most widely used building blocks in contemporary solid-phase synthesis of oligonucleotides. The accurate molecular weight measurements of such molecules, which are acid-labile compounds, may be easily determined by mass spe …
