The chemical formula of a base usually ends with hydroxide (OH). Bases can be gentle or very caustic. Examples of common bases: NaOH(aq) Mg(OH)2(aq) Ca(OH)2(aq) NH4OH(aq) Acids and bases can conduct electricity because they release ions in solution. Acids release hydrogen ions, H+ ...
This chapter introduces basic concepts of the properties of water, acids, bases, and buffers. Water plays a major role in all aspects of metabolism: absorption, transport, digestion, and excretion of inorganic and organic substances, as well as maintenance of body temperature. The unique ...
PH and Buffers. Polarity is the property of having two opposite poles. Salts, Acids, Bases and pH On a Scale of 0 to 14 pH Notes. Electrolytes Electrolytes are solutes that dissolve in water. The polarity of water breaks them apart to form ions. The resulting solution will conduct. Acids...
Most nurses shudder if they are asked a question about acids, bases or buffers and one can hardly blame them. Much of the complex terminology was devised many years ago and is now out of date. This chapter attempts to correct the situation by giving a simple modern account of the subject...

3.2.2Electrophoretic transfer (must use electrophoretic buffers) Decreases transfer time required Used with acrylamide or agarose丙烯酰胺或琼脂糖 Requires low ionic strength buffer Requires nylon membranes This system uses electric current to move the DNA transversely through the gel to the membrane. This...
The used palindromic linker probe is a short unmodified single-stranded DNA (ssDNA) that is complementary to the sequence of bases in the targeted nucleic acid strand as PCR template. In the presence of target template, the pre-formed duplex of the linker and the target DNA, in the region ...
