A positive control indicates the right mastermix set up and PCR program (if it worked). Stab with a needle straight in and straight out of the center of the tube half way down. Negative regulation: A decrease in the gene expression due to the presence of a regulatory element (negative regulator) is referred to as negative regulation. Purpose: Negative stains are used to view cell morphology and arrangement of microorganisms and selected because of the minimal damage and distortion of the bacterial structures. 7. Both materials form 3-dimensional matrices with pore sizes appropriate for separation of nucleic acids and are nonreactive with the samples. The specificity of these interactions is the key property that enables molecular circuits. a. One tube could contain the drug we want to test. 10. The Gram stain is a differential staining technique used to classify & categorize bacteria into two major groups: Gram positive and Gram negative, based on the differences of the chemical and physical properties of the cell wall.
