University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

Submit your completed lab report to the Lab: Photosynthesis Lab assignment link for grading. For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

salt solution is 6.3grams and the 15% salt solution is 6.8 grams. My hypothesis was that the carrot would shrink and be very small and gooey‚ but it was wrong. The controlled variable in this lab is the carrot and time‚ the manipulated variable is the salt solution‚ and the resulting variable in this lab is what happens to the carrot. Materials and Methods: . Salt solution ( 0-15%) . 4 Carrot pieces from same Carrot( Cut carrot in half if needed) . 4 Beakers . Water . Triple beam balance

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance
