I am trying to conjugate a plasmid DNA with an -SH activated PEG. The thiol group modification is possible for linear single strand DNA. I wonder if it possible to introduce in a plasmid DNA, too.
Hi, You should look at Klimasauskas work for this. Start with PMID: 23042683 and PMID: 28111014 .
I performed fluorescence stainings on brain formalin-fixed paraffin embedded samples (zebrafish). I stained TH+ neurons and counterstained with DAPI. In tissues coming from 2 specific animals,...

Consider the special case of the Gagliardo--Nirenberg inequality in R^4 $$ \|u\|_p \le C_p \|\Delta u\|_2^{1-4/p} \|u\|_4^{4/p} $$ with $p \ge 4$. What is the value of the best constant $C_p$?
