what is single chain variable fragment and what makes it help detect a protein like Her 2?
Homework Answers
Single chain variable fragment: It is a fusion protein consisting of variable regions of heavy and light chains of immunoglobulins joined together by a peptide linker( short peptide linker of 10-25 amino acids ).
They are used in detecting proteins like Her2 because:
- of their small size which facilitate the crystallographic study of cells interactions.
- they are highly immunogenic and have distinct antigens that extract antibodies specific for breast cancer.
- it can be designed as a bispecific antibody to work as immunotoxin.

Imagine a transmembrane protein consisting of a single polypeptide chain. The protein has alpha helices that pass through the membrane seven times. Between each segment that passes through the membrane are loops that extend into the cytoplasm or into the extracellular fluid. The C-terminus of the protein extends into the cytoplasm and the N-terminus extends into the extracellular fluid. What is the minimum number of polar stretches* in the primary structure of this protein? *polar stretches are contiguous regions of...

What is the likely results of running the following code fragment? Why? int *ptr = (int *) 0xfeedbeef ; *ptr = 0 ; Suppose a class uses a dynamically-allocated integer array, pointed to by an int* variable named data. The current capacity of the array is stored in the integer variable capacity. The following code fragment is meant to dyamically resize the array, doubling its capacity. What is the major memory error and how would you detect it? int *tmp...

What happens if the spliceosome makes a small mistake, such as inserting or deleting a single nucleotide from the final spliced mRNA? - Can mutations in the DNA destroy a splice site? What is the consequence for the protein if and when this happens? - Can mutations in the DNA create new splice sites? If so, what is the consequence for the protein?

Protein A binds to the IgGs of different species of animals with variable affinity. What does this difference tell you about the Protein A epitope? a. the epitopes of the species are identical b. Some species lack IgGs and therefore cannot bind to Protein A c. the epitopes are similar, but with enough difference that it makes the affinity variable. d. The epitopes are very different in all the species Provide reasoning with your answer. d.
