Protein Separation Using Gel Filtration Chromatography Introduction: Chromatography techniques are one of the most useful methods use for the isolation or separation of macromolecule from a mixture. The most common used chromatography techniques are thin -layer chromatography (TLC), column chromatography, etc. The purpose of this lab exercise is using the gel filtration chromatography to separate different proteins from a mixture based on their size. Also, collecting elutes that run through…

with alloxan induced diabetic rats and normal rats. The result of antidiabetic potential suggested that methanolic extract possess antidiabetic activity. Methanolic extract processed through bioactive fractionation as water soluble fraction and ethyl acetate fraction. The phytochemical investigation and antidiabetic activities was carried out on…

IR was also obtained for the final product. Overall, the 1H NMR data shows a decrease in (Z)-stilbene and an increases in (E)-stilbene. For the first fraction, the crude product, a ratio of (E)-stilbene to (Z)-stilbene was 1:1. This means that the crude mixture was half of the trans isomer and half the cis isomer. This ratio was determined by looking at the two singlets in the spectra RM-09-1 representing…

mixture that include continuity, momentum and mass fraction of the components, are solved at first. Transient conservation equations are as follow: Mass conservation (1) (∂(ε(1-s)ρ_g))/∂t+∇.(ρ_g u ⃗_g )=S_m In this equation u ⃗_g is superficial velocity vector of gas mixture, which related to intrinsic fluid velocity U as following: (2) (u_g ) ⃗=ε(1-s)U ⃗ In the gas transfer channel, the porosity is equal one and the liquid water volume fraction is zero; so in this area, the superficial velocity…

of trypsin. Future labs could benefit from having consistent samples of trypsin and Biorad. The conditions from the trypsin and biorad must remain the same throughout the experiment. Other suggestions include making dilutions from the original fractions and not from a separate test tube as that introduces new variables to the mix such as an uneven distribution of trypsin when making dilutions in a new tube. This experiment further dove into the multiple application of affinity chromatography…

multiple times some sections that caused a little confusion, but again it was not that bad and at the end everything came back to me, this time it was a lot easy for me to figure out some of the book samples, except of course the ones that had multiple fractions I am still under pressure with those.…

Cyclohexane was the more volatile liquid collected in fraction A. It is a more volatile compound compared to Toluene due to its structure, which compared to Toluene does not contain any double bonds nor does it have any dipole moments. Thus with a lower molecular weight and little to no intermolecular forces…

second phase, inflammatory pain response.” Rinaldi et al. (2008) observed that while none of the three treatments had an effect on the first phase, the first fraction (F1) reduced licking time. Lastly, the mice’s paws were injected with Carrageenan, Histamine, or Serotonin after they were pre-treated with the crude extract and its fractions. “Carrageenan induced rat paw edema is a traditional model to evaluate anti-inflammatory drugs,” and results showed that the crude extract did not inhibit…

significant part of the experiment was determining the protein concentration of the prepared mitochondrial fraction which will be further explained. The reason for that is by increasing enzyme concentration present in a sample, it can increase the enzyme's activity and that is what we are studying. We conducted a Bradford Assay to measure the protein concentration of the mitochondrial liver cell fractions.…
