Forms:

α. 1900s– electropherogram.

β. 1900s– electrophorogram.

Origin: Formed within English, by compounding. Etymons: electro- comb. form, electrophoresis n., -o- connective, -gram comb. form.

Etymology: < electro- comb. form + -pher- (alteration of -phor- in electrophoresis n.) + -o- connective + -gram comb. form. Compare slightly later electrophoretogram n.The reason for the alteration of the vowel in the stressed syllable in the α. forms is unclear.

Chiefly Biochemistry.

A record or chart produced as a result of electrophoresis.
