https://www.selleckchem.com/products/CI-1040-(PD184352).html Matrix-assisted laser desorption/ ionization (MALDI) is a soft ionization technique for introducing wide range of analytes into a mass spectrometer (MS). MALDI MS is a powerful tool in drug discovery research and development, providing a high-throughput molecular analysis technique in both preclinical and clinical systems. In particular, MALDI MS is invaluable in the study of peptides and proteins that drive all biological functions. This technology is label-free, provides high specificity in molecular identification, and is high-throughput. MALDI MS has been used in biomarker discovery and quantitation in virtually all tissues, serum, plasma, CSF, and urine for diagnostics, patient stratification, and monitoring drug efficacy. Other applications include characterization of biological drugs, spatial mapping of biomarkers and drugs in tissues, drug screening, and toxicological assessment.Bispecific antibodies combine the specificity of two antibodies into one molecule. During the past two decades, advancement in protein engineering enabled the development of more than 100 bispecific formats, three of which are approved by the FDA for clinical use. In parallel to protein engineering methods, advancement in conjugation chemistries have spurred the use of chemical engineering approaches to generate bispecific antibodies. Herein, we review selected chemical strategies employed to generate bispecific antibodies that cannot be made using protein engineering methods.Patient-reported outcomes (PROs) are quantitative assessments of a patient's perspective on their health and are derived directly from the patient, as opposed to clinician interpretation. PROs can serve as unique tools to improve health care providers' understanding of the patient's daily lived experience and highlight salient domains that are specific to children with chronic kidney disease (CKD). As such, PROs fill an important gap in achieving optim
