Hello world!

Most common mistake "I will remember how I got here". Take good NOTES!

Harvest .1 g of tissue, 100 micrograms of RNA from RNA isolation kit. Don't know we didn't sample the wrong part of the organ since the amount is so small. Be your hardest critic.

Isolated PolyA RNA (Ideally you get 2% of the RNA, protein coding) Fragment the RNA before synthesizing. DNA polymerase (reverse transcriptase) goes into mix, made cDNA. Primers for amplification, you make a hexamer, which is every possible combination so that the complementary bases will bind. Sequence cDNA that is the template to the RNA you are using. It is more stable.

Don't want full length DNAs, because we want about 75 bases for short reads. Randomly fragmented which is wonderful.

Gel purified and reamplified (picture in PP)

We are sampling a wadded up tissue looking for proximal and distal end. Could have gotten serosa, need to be aware that we had to leave it frozen in order to not lose the RNA we needed.

Looking for genes involved in the up regulation of the amino acids that were measured in Figure 3 from 1a_pay_B4_pumpping_1995.

Housekeeping genes for liver and intestines (always on genes so we know we got the right cell) Cell proliferation or cells growing (brush border growth, find these proteins) Uptake genes
