Question
Asked 28th Dec, 2017
How do I calculate the length in angstroms of a polyethylene glycol chain where n=22 (M.W. = 1,000 Da)?
I have purchased a heterobifunctional PEG crosslinker with M.W. 1,000, and a PEG repeat of n=22. I would like to know how to approximate the length of the polymer given the number of PEG repeats. Is there a conversion factor?
Thank you.

A very short introduction:
A more sophisticated ntorduction but still with manageable size:
And some excercises:
My opinion it is much more instructive to go through such papers than just to ask for a conversio factor.

Thank you for your thoughtful response, I am indeed learning a lot from the references you have provided. This is a case where I didn't know what I didn't know, i.e. this is a deeper topic than I realized.

How to cite clinical trials using Endnote?
I use Endnote X9 on PC, and am trying to cite clinical trials from https://clinicaltrials.gov/.
I downloaded and saved the clinicaltrials filter for endnote. I downloaded the relevant file as plain text from clinicaltrials.gov, and imported it to Endnote. But I cannot find it in my Endnote library. No error message appears either.
I basically followed this tutorial step by step,
Two observations,
1. My page from the Clinicaltrials website (screenshot below) seems different than the one shown in the video at 0:32.
2. The downloaded plain text file in the tutorial (shown at 2:16) seems to have way more details than mine, which only shows NCT number.
But the problem is, when I try to download a relevant file for a clinical trial (no matter ongoing or completed trial), I see this message,
'''Data Fields
Currently only NCTId field is available to download for Text format''.
I suspect this is the problem, but any idea how to go around it?
thanks

These equations make it possible to evaluate the relative react...
