A: Isolate HHHHHHH
Method: Ni-Affinity Chromatography
Reason: Six histadine amino acids at the end of the protein can bind to nickel very tightly. Nickel can bind to agarose bead very tightly. Use this strong affinity column we can isolate our protein, which has seven histadine amino acids.
Buffer condition:
His-binding buffer:
• 50 mM Tris-HCl (pH8.0)
• 5 mM Imidazole
• 100 mM NaCl
• 0.1 mM EDTA
• 1 mM PMSF made fresh
His-wash buffer:
• 50 mM Tris-HCl (pH8.0)
• 300 mM NaCl
• 15 mM Imidazole
• 0.1 mM EDTA
• 1 mM PMSF made fresh
is-elution buffer:
• 50 mM Tris-Cl (pH8.0)
• 50 mM NaCl
• 300 mM Imidazole
• 0.1 mM EDTA
• 1 mM PMSF made fresh
Procedure:
1. Ni-Agarose Beads Preparation:
1L mixture proteins will need 25 ml of beads.Transfer beads into a column. Wash the column by His Elution Buffer then wash by His Binding Buffer.

Since our protein has seven histadine amino acids and no other amino acids present so the protein should have high affinity, in this way we will use column binding instead of batch binding to purify protein. Flow the mixture through the column. Save small amount of eluate.
3. Wash beads with His Binding Buffer. Save small amount of eluate.
4. Wash the column with His Wash Buffer. Check
flow through with quick bradford. Continue with the His wash buffer until no detectible protein is found
in eluate which means all of the weakly binding proteins are washed away.
5. Elute the protein with His Elution Buffer. Save all
Results The lab experiment was done in two parts, one with the NAND, NOR, XOR and Hex Inverters and the other with a 7483 full adder gate, both will verify the truth table when two input bits and a carry are added together. The circuits were built by examining the 1 bits through a K-Map to create a Boolean expression for the sum and carry. The Boolean expression for the sum was A⊕B⊕C and the carry as AB+BC_in+AC_in. From these two expressions, we notice that we must use two exclusive-ORs gates in the sum inputs for A, B, and C. For the sum, we have to use NOR and NAND (the only available gates from the lab manual).
For most sequences at position 4 and 5 we observe only the nucleotides G and T, respectively. There may be rare cases where other nucleotides may also be found. To consider such observations, we need to do a process called additive smoothing or Laplace smoothing to smooth the categorical data. [9] In this case, we add 4 sequences: AAAAAAAAA, CCCCCCCCC, GGGGGGGG, TTTTTTTTT.
I need to find the area of rectangle ABCD. I know that ABCD is a rectangle with diagonals intersecting at point E. Segment DE equals 4x-5, segment BC equals 2x+6, and segment AC equals 6x. I predict that To find the area of rectangle ABCD I need to find out the base and height of the rectangle. The first step is to find what x equals. Since I know the intersecting line segments AC and DB are congruent that means when I times the equation 4x-5 for segment DE by two it will equal the equation 6x for segment AC.

The purpose of sludge was the following: To use lab skills learned throughout the year to separate and identify each pure substance in the original mixture. The sludge that was given to the group had the name of Ramos. The mixture of Ramos was a dark, orange, murky liquid that had a few objects floating around in it, such as (or hypothesized as) orange blocks, and tiny ‘metal’ rods. The mixture also had a substance that looked like, and appeared to be, sand. These were all able to be separated and identified using the two labs stated below, without getting into specifics.
Figure 20 and 21 casting tray Figure 22 gel box After 1 hr., take out the gel from gel box carefully, place it into the machine, so that the DNA gel electrophoresis can be visualize under UV light. Figure 23 gel documentation system, used to visualize gel electrophoresis with UV light NMR spectroscopy First of all, 3 samples were prepared, peptide in SDS, DPC, and buffer. The sample temperature was maintained at 298 K, prepared by supervisor and H(hydrogen) in SDS and DPC micelle was replaced with D(deuterium) , so that in proton NMR, peptide won’t be interfered by H in micelle. amount of peptide in sds and dpc
After eight to ten minutes of the chromatography, paper strip is in the chamber the pigment and solvent will start to travel up the paper strip, make sure to allow the paper to dry before getting results. Repeat the steps above but instead use two separate reaction chambers and add in separate tubes developer two (Isopropyl) and developer three (Isopropyl and
One sample had 250ng of plasmid A as well but with no enzymes added. All the digestions tubes were incubated at 37℃ for 30 minutes. After incubation, 5μL of loading buffer (30% glycerol, 10 mM Tris-HCl, pH 8, 1 mM EDTA, 0.025% bromophenol blue) was added to each sample. 50 ml of molten agarose (1% agarose boiled and cooled to 55℃ with added SYBRsafe) was poured into the casting tray for gel electrophoresis.
1 “substrate” and another “ enzyme.” Instead of using the distilled water, this time you are going to use different pH buffer in the enzyme test tube. In the substrate tube, add 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL of guaiacol for a total volume of 7.5 mL. For the enzyme tube, instead of distilled water add the pH solution (3) and 1.5 mL of peroxidase which equals a total volume of 7.5 mL. Use the dH2O syringe for our pH solution. To clean the syringe, flush it by drawing 6 mL of distilled water.
After, the pellets were removed, 5 drops of Enzyme Color Reagent went into

1.1 Abstract The purpose of quantitative analysis of protein using a spectrophotometer is to measure the concentration of proteins in a given sample. The experiment is conducted by laboratory method (Biuret Test) and using spectrophotometer to analyze the absorbance of reactants at 540 nm, hence determining the concentration of the proteins in a given sample. The purpose of stopped enzyme assay to study B-galactosidase is to determine the effect of temperature and concentrations of substrate on enzyme activity.
It is the only macromolecule that is going to dictate the nature of the protein to be
