Antagonistic Pleiotropy (AP) is today the best-accepted theory for the evolutionary origin of aging. According to AP theory, aging is a side effect of genes that are selected for their contribution to fertility and other essential components of individual fitness. In this standard view, aging exists because the benefits of enhanced fertility early in life are linked logically or physically to the long-term deterioration of the body, and evolution has been compelled to accept the latter as a cost of the former.

How to do deep-learn the FPLC (superdes)
1. Filter – change to a new filter
2. Beads
a. Organic solvents – wash off hydrophobic molecule
b. H2O
c. NaOH 0.5M
d. H2O
e. Acid - acetic acid
f. H2O
2. Exceed pressure limit – the resin will be compressed
3. Repack column – need two columns

Difference between FPLC and HPLC
HPLC: purify protein of small volume with a higher precision
FPLC: Fast protein liquid chromatography – used for purification for protein of large volume

ME buffer: MOPS/EDTA Buffer, 10X Liquid Concentrate is a clear, colorless liquid. Prepared with DEPC for RNA applications. 10X concentrate contains 200 mM MOPS, 50 mM EDTA, 21 mM sodium acetate, pH 7.0 at 25 °C. A commonly used buffer for RNA electrophoresis in denaturing (formaldehyde) agarose gels.
