For biochemistry lab we did gel filtration chromatography purification of LDH. The directions I've been given say
to determine Ve the elution volume for LDH from the peak of a plot of A340/min vs fraction number. It says if ours ''didn't work out'' to consider the middle fraction of my pool as the peak. My pooled fractions were 43 through 49. I understand that the elution volume is the volume from the time the LDH was applied to when it elutes. I applied the LDH at fraction 6 and each fraction was 1 mL. Would the Ve be the highest peak at fraction 44 or would it be at the second peak above fraction 47?
The highest Ve is the highest peak at fraction 44. The elution volume is the volume of eluent required to cause... View the full answer
