Homework Answers
Biotinylated secondary antibodies are used in immunoassay techniques where signal amplification is highly required. Biotin has a very high affinity to bind to streptavidin. Generally, In an immunoassay experiment, as the biotinylated secondary antibodies binds to the target molecule, streptavidin is put, so as to have a high signal amplification.

Avidin binds biotin with a Kd of ~10−15 mol/L. A protein of interest can be covalently linked to biotin and subsequently isolated by incubating with beads coated with avidin. If the concentration of biotinylated protein is 10-8 M at the beginning of the assay and the beads provided an excess of avidin-binding sites, then one could expect the beads to bind: a. Less then half of the biotinylated protein will be bound to the beads. b. Exactly one-half of the...

How would you put this in a financial calculator to get the interest rate
How would you put this in a financial calculator to get the interest rate?This question illustrates what somewhat unscrupulous lender. You want to borrow $29,000 for one year. The interest rate is 19.5 percent. You lender agree that the interest on the loan will be .195x $29,000 $5,655. So, the lender deducts this interest amount from the loan up front and gives you $23,345. In this case, we say that the discount is known as discount interest. Imagine you are...

(Hint: this control experiment cannot be done in crayfish but only in animals that can be genetically modified, e.g. mouse, Drosophila) naptic protein and you get labeling in an unexpected location (neuronal nuclei).
