Abstract The molecular weight measurement of intact Escherichia coli proteins separated by isoelectric focusing-immobilized pH gradient (IEF-IPG) gels and analyzed by mass spectrometry is presented. Two methods are discussed: (i) electrospray ionization (ESI) mass spectrometry (MS) of extracted ...
important considerations for therapeutic drug formulation and storage. Biotherapeutic drugs can be analysed at their subunit level following reduction and/or digestion. Analysis of therapeutic antibody subunits facilitates exact molecular weight analysis ...

Intact mouse IgG1 protein purified by Protein-A with a known molecular weight Used as the unlabeled, control/reference standard for the GlycoWorks RapiFluor-MS N-Glycan sample preparation workflow as it has 4 major glycosylated peptides Provided in a Waters TruView Vial (ideal for peptides)...
performance checking (e.g., myoglobin) are not well suited to check the instrument performance when the analysis of monoclonal antibody is needed because analytical (instrument) conditions may greatly deviate from that for mAb analysis due to molecular weight and structure difference (e.g., ...
For a monomeric protein analyzed by MS, differentiation of its conformation changes is somewhat more challenging, given that species will possess the same molecular weight regardless of folding status. It is possible, however, based on the difference in the charge envelope to extract quite ...
Intact-MS (Intact protein mass spectrometry) technology is used to determine the exact mass of protein molecules, and it is an ideal method to screen covalent binding compound library. When a compound is covalently bound to the protein, the corresponding molecular weight of the protein molecule wi...

(S) was determined and used to calculate the molecular weight (MW) of each component in solution. The estimated MW of the complex was compared to the MW of PE alone and used to estimate the molar binding ratio of TCR:PE (n), as shown in the table below.BOn a separate SV-AUC ...
Although each PEG-mal used was 10 kDa in size, the molecular weight shift it caused was about twice, as noted previously50. d, Liposome pelleting assay. GSDMD insertion mutant (F184D/L186D) was designed from the GSDMD pore structure8, which should bind to the membrane but does not ...
