Why am I seeing a doublet at 100 kDa when using your Grp94 antibody for western blot?

It is possible to see a doublet at ~100 kDa for Grp94 due to post-translational modifications. Here is a link to our PhosphoSitePlus database detailing the possible post-translational modifications for Grp94: https://www.phosphosite.org/proteinAction.action?id=6928&;showAllSites=true.
