comment How to calculate virus titre from qPCR
I'm still not clear why you are trying to titre viral pfu using the manufacturing system (HEK293T cells) rather than your intended experimental system? Infectivity is certainly a function of host cell, but only makes sense in your experimental system. I guess my question is, why is a plaque assay system that difficult to use? Perhaps I have not understood some nuance of your particular system.

comment Are there special constants in biology that define organism's morphology?
There are 20 references concerning facial symmetry and the golden ratio indexed on PubMed, and nearly 800 mentioning the golden ratio itself. I'm not sure there will be scientific evidence per se, since that would require experimental evidence. Instead, most of what I've seen about the golden ratio (or the associated logarithmic spiral or golden angle) are observational reports. The significance of this number is debated, but I don't see any arguments discounting its existence.

comment Dimerization of Immunoglobulin G
What's the nature of the hydrogen bonds/non-covalent bonding between two heavy chains? Are they naturally aggregated in the cell?

comment Dimerization of Immunoglobulin G
No, of course each immunoglubulin-like domain has an intramolecular disulfide (stabilizing the beta sandwich conformation). I mean between two heavy chain molecules.

Thanks for the suggested article. I'm not able to get it through my institution, do you have a copy, or can you quote the relevant results?

Hi @fedslaur, I have made some corrections to your spelling/grammar to make it read more easily. I have made sure to keep the nature of your question.
