Intact cell MALDI mass spectrometry biotyping for "at-line" monitoring of apoptosis progression in CHO cell cultures
Background Mammalian cell cultures, especially Chinese Hamster Ovary (CHO), are the predominant host for the production of biologics. Despite considerable progress in industry and academia alike (also enforced e.g. by the Process Analytical Technology Initiative of the FDA), particularly in the field of process monitoring there is still a need for innovative methods enabling improvement of proc...
متن کاملUsing Spores for Fusarium spp. Classification by MALDI-Based Intact Cell/Spore Mass Spectrometry
Fusarium is a widespread genus of filamentous fungi and a member of the soil microbial community. Certain subspecies are health threatening because of their mycotoxin production that affects the human and animal food chain. Thus, for early and effective pest control, species identification is of particular interest; however, differentiation on the subspecies level is challenging and time-consum...
متن کاملCharge monitoring cell mass spectrometry.
An instrument to directly measure the charge carried by a cell or a microparticle as well as mass-to-charge ratio of the cell/microparticle was developed for rapid mass distribution measurement. A successful mass spectrum with a record high mass has been demonstrated. In this article, the details of the construction and operation of the charge monitoring cell mass spectrometer are reported. Exa...
متن کاملGeneration of CHO Stable Cell Line Overexpressing HER2: an In Vitro Model for Breast Cancer
Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...
متن کاملEstablishment a CHO Cell Line Expressing Human CD52 Molecule
Background: CD52 is a small glycoprotein with a GPI anchor at its C-terminus. CD52 is expressed by Normal and malignant T and B lymphocytes and monocytes. There are detectable amounts of soluble CD52 in plasma of patients with CLL and could be used as a tumor marker. Although the biological function of CD52 is unknown but it seems that CD52 may be involved in migration and activation of T-cells...
