Immunostaining using Quantum Dot fluorescence reveals that there are 5 CFTR channels/μm2 in the “CONTROL” and 81 CFTR channels/μm2 in the “CFTR-CRISPR”. Calculate the number of moles of Cl-transported per channel per second for both treatments. Note that there are 1x108 μm2 in each cm26. Explain the difference between uniporter, antiporter, and symporter carrier proteins.1) A) List 15 drugs (monoclonal antibodies can be used) used clinically to treat cancer in humans. These targets must be signal transduction pathway components. B) For each drug, list the specific protein targeted. C) For each drug, describe the efficacy of treatment (i.e. what is the success rate in life extension) as well as appropriate cost of treatment whether it be per round or an average annual cost.

Don't copy A) It has more rapid onset than vecuronium B) It has the same mechanism of action as succinylcholine C) It is the least cardiac stable neuromuscular blocking agent D) It has a significantly longer duration than vecuronium?1. True or False: Antibodies for Western blotting can be applied directly to the SDS-PAGE gel.1.a)What is the equivalence point and how does it relate to the recommended proportion of serum to blood in the heme agglutination assay? b. what would the predicted outcome be if you used too little serum in this assay?

Then aside from hematoxylin, what dyes are commonly used in preparing histological slides? List and indicate when the dyes can be used, or on what samples can the dyes be used.1) You have been asked to engineer a protein (which is not animmunoglobulin) that is capable of binding to a given protein target.Devise a strategy and discuss the main molecular screeningapproaches required.If I purchase a mouse anti GAPDH antibody what will it bind to?
- Give 5 storage conditions of human normal immunoglobulin injection and why?(1) In antibody structure, where are can we find unique variable domains? A. at the tip of each polypeptide chain B. on the stem region of the antibody C. at the bottom of each polypeptide chain D. only on immunoglobulin E (2) The stem region of the antibody determines the: A. general immunological mechanism of action B. specific inflammatory response C. specific immunological mechnism of action D. shape of the variable domains (3) Antibodies are proteins that consists of ------ polypeptides in a ------ shaped structure. A. three, X B. four, Y C. five, clover D. two, YWhen a mixture of different IgG antibody proteins are treated with the enzyme papain, each antibody is cleaved into three roughly equal size fragments. From each original antibody, two of the three fragments are identical to each other, and represent the ‘arms’ of the antibody ‘Y’. These fragments are known as Fab fragments. The third fragment is known as the Fc region, because this fragment will crystallize when purified. The reason a mixture of Fc fragments will crystallize is because: It is the only part of the antibody protein that can easily be purified at the high concentrations needed for crystallization. It has no disulfide bonds holding the domains together, as disulfide bonds will inhibit crystallization. It is the only fragment of the antibody that still has disulfide bonds, so it remains intact during the crystallization process. The Fc fragments of IgG are much more water soluble than the Fab fragments. All Fc fragments generated from a mixture of IgG molecules have the…
