Analytics of the therapeutic peptide aviptadil by sheathless CE-MS and comparison with nanoRP-HPLC-MS.
Purification and quality control of therapeutic peptides is often performed by one single method, RP-HPLC. As usage of an orthogonal technique is highly advisable for quality assurance, capillary electrophoresis (CE) employing a coated capillary coupled via a sheathless interface to a mass spectrometer was applied in parallel. The basic therapeutic peptide aviptadil served as a…Read More
The ant Paraponera clavata (Fabricius, 1775) is the only extant species of Paraponerinae and is widely distributed in Brazilian forests. Aspects of its biology are documented extensively in the literature; however, knowledge of P. clavata internal morphology, specifically of exocrine glands, is restricted to the venom apparatus. The objective of this study was to describe…Read More
The incidence of high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements in diffuse large B-cell lymphoma
Goal: To research the incidence of high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangement in Chinese language diffuse massive B-cell lymphoma (DLBCL) . Strategies: From January 2013 to August 2020, 922 DLBCL instances have been collected. C-MYC and BCL2 protein expression ranges have been analyzed by immunohistochemistry staining. Fluorescence in situ hybridization was used to detect…Read More
