Antibody-free LC-MS/MS quantification of rhTRAIL in human and mouse serum.

The major challenge in targeted protein quantification by LC-MS/MS in serum lies in the complexity of the biological matrix with regard to the wide diversity of proteins and their extremely large dynamic concentration range. In this study, an LC-MS/MS method was developed for the simultaneous quantification of the 60-kDa biopharmaceutical proteins recombinant human tumor necrosis factor-related...

Rapid Quantitation of Substance P in Plasma Using Differential Mobility Spectrometry and Micro flow Liquid Chromatography An exceptionally selective and sensitive strategy for high throughput peptide quantification is presented by coupling DMS (Differential Mobility Spectrometry) technology with μLC/MS/MS analysis

• Impaired sensitivity in complex matrices – Very low-level peptide detection (sub-pg/mL) can be suppressed by high background and competing ions in biological samples. • Lack of throughput – Complex biological matrices hamper data resolution and require sophisticated sample preparation and/or advanced instrumentation. • Limited quantitation range – Poor MS/MS sensitivity combined with often po...

A sensitive multidimensional method for the detection, characterization, and quantification of trace free drug species in antibody-drug conjugate samples using mass spectral detection

Conjugation processes and stability studies associated with the production and shelf life of antibody-drug conjugates (ADCs) can result in free (non-conjugated) drug species. These free drug species can increase the risk to patients and reduce the efficacy of the ADC. Despite stringent purification steps, trace levels of free drug species may be present in formulated ADCs, reducing the therapeu...

The Reaction of Placental GRP78 Protein with Sera from Women with Multiple Sclerosis

  Background: Multiple Sclerosis (MS) with four different types is one of the well studied autoimmune diseases of the central nervous system. Generally, two-thirds of MS patients are females who are at risk of pregnancy-related complications. Inappropriate responses of mother’s immune system, such as antibody production against placental proteins, may lead to pregnancy-related disorders. The as...

Plasma Free Metanephrines Quantitation with Automated Online Sample Preparation and Liquid ChromatographyTandem Mass Spectrometry

Recently, we reported an LC-MS/MS method for measuring Pmets using ion-pairing solid phase extraction (IP-SPE) and porous graphitic carbon (PGC) column chromatography1, 2. Although the method is fast and analytically sensitive, it can be further improved by automating the offline sample preparation with online sample preparation technology, which is more timeand cost-effective. Thermo Scientifi...
