This requires a chemical fixative. Crosslinking fixatives act by creating covalent chemical bonds between proteins in tissue. This anchors soluble proteins to the cytoskeleton, and lends additional rigidity to the tissue. Preservat… good system cleaner

WebThe buffer capacity is the amount of acid or base that can be added to a given volume of a buffer solution before the pH changes significantly, usually by one unit. Buffer capacity depends on the amounts of the weak acid and its conjugate base that … WebBuffers typically consist of an acid-base pair, with the acid and base differing by the presence or absence of a proton (a conjugate acid-base pair). For instance, one of the buffers that maintain the pH of human blood involves carbonic acid (H _2 2 CO _3 3) and its conjugate base, the bicarbonate ion (HCO _3 3 ^- − ). chevrolet factory wheel take offsWebCh. 25 Fluid and Electrolytes. 86 terms. dorkdork.
