Question

The specific refractive increment of some purified proteins

Answer 1

Publication trends show that the fastest growing method for immunoprecipitation incorporates the use of magnetic beads and that Invitrogen Dynabeads products are the most used and referenced products in this trend. Why? Because Dynabeads magnetic beads offer you the best balance of capacity/yield, reproducibility, purity, and cost for smaller-scale isolation of specific proteins (e.g., immunoprecipitation, IP) and protein complexes (co-immunoprecipitation, co-IP).

Protein purification and research needs have changed considerably since the introduction of the agarose-based "Sepharose slurry" in the 1970’s when the focus was purifying large amounts of protein or antibody. If this is your primary application, agarose/resin-based columns still work well

Answer 2

Explanation:

$\huge\underline\mathfrak{\red{ANSWER}}$

It can be observed that ΔBQC and parallelogram ABCD lie on the same base BC and these are between the same parallel lines AD and BC.

∴Area (ΔBQC) = 1/2 Area (ABCD) ... (1)

Similarly, ΔAPB and parallelogram ABCD lie on the same base AB and between the same parallel lines AB and DC.

∴ Area (ΔAPB) = 1/2 Area (ABCD) ... (2) From equation (1) and (2), we obtain Area (ΔBQC) = Area (ΔAPB)
