It stands for periodate, lysine and paraformaldehyde, which
are 3 of the ingredients used to make up the solution. Once
they are all dissolved, the fixative does not actually contain 
any lysine or any paraformaldehyde. It is supposed to
cross-link cell surface glycoproteins, and it may do this,
but not in the way proposed by the originators of PLP.
I wrote about this, with references, in response to a 
Histonet enquiry a few months ago; it should be in the archives.
