How much of a 10 mg/mL lysozyme stock would you need to add to 4 mL of cells for a final concentration of 1 mg/mL? What is the lysozyme doing?6-One method to determine proximity of two locations in a protein molecule or protein complex is FRET. This technique uses fluorescence transfer between two fluorophores where the ability of the transfer to occur is correlated to distance between the two residues. A) On the following graph using colored pencils, pens, or markers draw the emission spectra from the donor and the absorbance spectra of the acceptor (this should be a general schematic, does not need to be a FRET pair). Include a key for your graph B) As a rescarch student in my group you want to study the proximity of two residues in clamp region of a protein. Draw a schematic of your protein and label the two locations of your fluorophores. In 2-4 sentences (or figures) explain how your FRET fluorophores would give determine if these two residues were close to one another.
- Question:- Explain how the following components contribute to the ideal multifunctional liposome: 1. phospholipid matrix 2. destabilizing lipid 3. conjugation lipid 4. ligands attached via conjugation lipid 5. cell death marker 6. chemotherapeutic agent 7. imaging agentVI. Although most biologically relevant sugars have the D-configuration, L-fucose is a commonly observed monosaccharide component in glycoproteins. Glycosylated antibodies (IgGs) observed in patients with active TB have more fucose than those found in patients with latent TB (Lu et. al., 2016). Latent TB occurs when a person has the TB bacteria, but bacterial proliferation is kept under control by the body's immune system; hence, the infected person is asymptomatic and not infectious. A person with latent TB will test positive for the tuberculin test or TB blood test. a) L-fucose is also known as 6-deoxy-L-galactose. Note that D-galactose is a C-4 epimer of D-glucose. Draw the Fisher projections for D-glucose, D-galactose and L-fucose. (Hints: D- and L-isomers are enantiomers. 6-deoxy means that the hydroxyl group at C-6 is removed leaving just the methyl group). D-galactose: D-glucose: L-fucose (6-deoxy-L-galactose): b) L-fucose can cyclize into a pyranose and form two anomers. Draw…Choose from A-F.
