Abstract: To allow control over injected genetically engineered cells, it is helpful that the genetically engineered cells express a marker that can be used to detect such cells among a pool of unmodified cells. Some embodiments relate to a marked protein comprising a TCR constant domain and an exogenous amino acid variation that comprises a sequence that is detectable and identifiable within the TCR constant domain. Other embodiments relate to an antibody epitope that is attached to a TCR chain. Both the marked proteins and the antibody epitopes can be used to track genetically engineered cells.

Abstract: Various embodiments are disclosed herein relate to methods for selection of a genetically engineered cell. Some embodiments relate to a cell that is produced with the methods disclosed herein.

Abstract: The present invention relates to a multi-branched Mannich base corrosion inhibitor and the method for preparing thereof. The method comprises (1) adding 3˜7 moles ketone and 3˜7 moles aldehyde to reaction kettle, adjusting pH to 2˜6 with acid, controlling temperature to 20˜50° C. and stirring for 20˜30 mins; (2) adding 1 mole organic polyamine to the reaction kettle under stirring, or adding the pH-adjusted ketone, aldehyde and organic solvent to organic polyamine, controlling temperature to 60˜90° C. and reacting for 1˜3 hrs, and after completion of the reaction, heating the system to 110° C. under nitrogen to remove water; the organic polyamine is organic compound comprising three or more primary amine groups and/or secondary amine groups.

Abstract: A mannich-base inhibitor for decalcification, a preparation method and application thereof are provided. The inhibitor comprises 10-80% mannich-base component calculated in the total weight percent of the inhibitor, while the rest is at least one compound selected from imidazoline inhibitor with molecular weight between 110 and 750, and alkynyloxy amine inhibitor. The mannich-base inhibitor component is prepared through mannich reaction with 1 mol organic polyamine containing three or more primary amine bases and/or secondary amine bases, 3-7 mol ketones, and 3-7 mol aldehydes. The inhibitor which can be effectively compounded and cooperated with oil demulsifying agent and oil decalcifying agent, have the advantages of stable property, strong absorbability, high film strength and film density with its inhibition rate exceeding 90%.
