Аббревиатура «НПХ» расшифровывается как нейтральный протамин Хагедорна – вещество, созданное датчанином Хансом Хагедроном, отличительной особенностью которого является равное (изофанное) содержание искусственно синтезированного инсулинового человеческого гормона и протамина.

Есть еще один термин, который также полезен в понимании того, что такое "(суб)изофанное содержание": isophane ratio

https://www.jstor.org/stable/3001435
The isophane-ratio is that ratio of insulin to protamine which results in equilibrium amounts of insulin and protamine remaining in the supernatant as tested by nephelometric procedures.

The term "isophane ratio" is the equilibrium amount of protamine necessary to complex with the analog as taught by Krayenbuhl and Rosenberg, STENO MEMORIAL HOSPITAL REPORT (COPENHAGEN), 1:60 (1946). The isophane ratio is determined by titration in a manner well known in the art and described in Krayenbuhl, et al.
