Absorption of e coli antibodies 5-17-12
2014-08-29azim58 - Absorption of e coli antibodies 5-17-12
I would like to absorb the e coli, GST, and CpG antibodies from the
SMC1fs sera (see SMC1fs Immunization Timeline) (note that alum was also
used as an adjuvant, but I do not think it is possible to raise any
antibodies against alum which is just a type of aluminum hydroxide
(KAl(SO4)2ยท12H2O)), and I would like to absorb the e coli antibodies
from the 4T1 and naive sera. Then I would like to reapply this sera to
the nitrocellulose tumor cDNA expression library array.
Before absorbing any antibodies, I will do an ELISA to measure the
antibody response to start with. Then I will absorb the antibodies. Then
I will check the effectiveness of the absorption by doing another ELISA.
see ELISA Protocol
After the primary is incubated for 1 hr, I will transfer the primary to a
new plate coated completely with SMC1fs to see how much SMC1fs antibody
was removed by the various incubations. I need to figure out which e coli
lysate I will use.

I also coated another plate that was completely coated with GST-SMC1fs
protein.

I used the wrong kind of plate (round bottom assay plate), and I will
need to repeat the experiment. I should have used a flat bottom Maxisorb
Nunc plate.
