Transformation of pGLO in E. coli: 8) Explain your expected results on LB, LB+Amp, and LB+Amp+Arabinose plates for the -pGLO and the +pGLO treatments. (6 total results, please assume everything works) Please describe how much growth, and whether if will or won’t glow.

please help? its biochemistry What are the masses (in kDa) of some of the most predominate contaminating proteins seen in the purification?

1CFD CALCIUM-FREE CALMODULIN How long is the protein’s primary sequence?Does this protein have any secondary, tertiary and/or quaternary structures present?Are there any molecular additions to this protein that are not amino ac

Enzyme Kinetics question Enzyme used is 10uL of a 10 ng/uL solution  to a reaction mix in a final volume of 2.0 mL. (Enzyme used is 20kDa monomeric enzyme if matters) Based off lineweaver burk where 300 uM of inhibitor is used noninhibited formula is y= 4x + 0.1 (x axis is 1/S 1/mM) (y axis is 1/Vo sec/mM) inhibited formula is y = 4x + 1   I found Km as 1 mM for inhibited Vmax as 1mM/sec for inhibited   How would I find Kcat? How would I find Ki?

GEL FILTRATION: What would you expect to be the effects on (a) the height of the peaks and (b) the volume between the peaks if the length of the Sephadex column were doubled? Please explain.
