John Jacob Abel to successfully isolate the neutral base of epinephrine by adding ammonium to highly concentrated extract, a method Abel himself tried but failed due to the use of low concentration of extract. After Takamine's success, Abel himself remarked, with great candor, "The efforts of years on my part in this once mysterious field of suprarenal, medullary biochemistry, marred by blunders as they were, eventuated, then, in the isolation of the hormone not in the form of the free base but in that of its monobenzoyl derivative."

He was married three times; the remains of his second wife Maria Hummel (1635–1681) were discovered in front of the Basel Minster in 2009, in what was Abel Socin's family grave, along with elaborate jewelry described by archaeologists as masterpieces from the era.
