A tube of broth containing tryptophan was inoculated with a loop full of bacteria for the indole test. After incubation‚ two drops of Kovac’s reagent was added to this tube and the color of the drops was recorded. All of the tests above were incubated for 24 hours‚ with the exception of the citrate test which incubated for 48 hours at 37° C‚ the results were subsequently

Aldol Condensation Discussion: 1. Aldol condensation reactions take place in basic conditions‚ where a deprotonated enol becomes an enolate and proceeds to attack the aldehyde. Since the solution is basic‚ it is able to deprotonate the alpha carbons of the product‚ which forces the hydroxide groups to leave. The product is then considered to be dehydrated and unsaturated. In terms of our reaction‚ cyclopentatone is deprotonated to form an enolate‚ which then attacks the two molecules of p-tolualdehyde

Fractions of 2mL were collected and the purity was assessed by 10% SDS-PAGE. 3.5 Determination of the Concentration of the DNA Polymerase SK72 The amount of protein was measured using the commercialized Bradford reagent as described by Bradford (1976). A standard curve was plotted in a range 100-1000ug/mL in a Bradford-compatible buffer using bovine serum albumin as substrate (Appendix A). 1mL of the dye solution was added to 20uL of the protein sample‚ mixed and
