Carsons Mordant . substance’s or metals that act as a link between dye and tissue A mordant is a metal with a valency of at least two. The two commonest metals used in histotechnology are aluminum and ferric iron, both with valencies of three. The attachment of mordant to dyes is by means of a covalent and a coordinate bond. Fixative additive fixation- stabilizes proteins by denaturing proteins (chemical, heat) and combines with fixative molecule becoming insoluble non additive ...

What are the three types of membrane proteins? correct answer: 1) Peripheral 2) Integral 3) Lipid anchored What are peripheral membrane proteins? correct answer: - Adhere to surface of lipid membranes or integral membrane proteins through non-covalent interactions - Can be removed using milder conditions What is the signature amino acid sequence for amphipathic helices? correct answer: P-P-NP-NP-P-P-NP-NP alternating polar and non-polar aa What are integral membrane proteins? ...

ACS BIOCHEMISTRY EXAM QUESTION WITH COMPLETE SOLUTIONS LATEST 2024. Henderson-Hasselbach Equation - CORRECT ANSWER - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - CORRECT ANSWER - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the Nterminus. Salting Out (Purification) - CORRECT ANSWER - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. ...

PURIFICATION OF GFP FUSION PROTEINS WITH IMAC IN E. Coli CELLS ABSTRACT This report was performed to demonstrate techniques of purifying Green Fluorescent Protein (GFP). The main technique used for demonstration is by Immobilized Metal Affinity Chromatogrpahy (IMAC). The open reading frame for enhanced green fluorescent protein was subcloned into the pQE30 expression. The subsequent production of protein tagged N-terminally with hexahistidine, facilitated the purification by IMAC
