A highlight of the afternoon session on non-chromatographic processing
and alternative media was the talk of Anja Trapp from Rentschler (Lau-
pheim, Germany) on caprylic acid based impurity precipitations for down-
stream processes. The precipitation step was implemented in a two-co-
lumn antibody purification process after Protein A capturing to precipitate
host cell proteins and product aggregates. The presented results demons-
trated that Caprylic acid precipitation can be an excellent alternative to a
chromatographic polishing step.
The third day of the conference was a very entertaining experience for all
participants. Every attendee was encouraged to contribute to the program.
In the morning, we participated in two sessions of round table discussion.
Up to 10 participants per table were requested to exchange their ideas and
thoughts about current trends, challenges and the future of hydrophobic
technologies and to summarize their discussion in one sentence.
Hydrophobic interaction chromatography (HIC) was the topic of the first
session while alternative hydrophobically influenced processing technolo-
gies were discussed in the second session. Discussions were very lively
and leading to interesting statements.
A new item on the agenda of the HIC/RPC conference was the announce-
ment of the first HIC/RPC Conference Dr. Yoshio Kato Memorial Award.
Dr. Kato’s lifetime dedication to the bioseparation field at Tosoh Biosci-
ence led to many commercial products employed in various analytical and
downstream purification applications. The award was presented to Profes-
sor Milton Hearn, Monash University, Australia, as esteemed scientist and
recipient of numerous awards and honors and long-standing fellow and old
friend of the HIC/RPC conference.
In keeping with tradition, the conference offered not only a high class sci-
entific program but also various opportunities to network with colleagues.
The guided desert tour on Wednesday afternoon was the highlight of the
social program of the Conference. We headed out deep into the Sono-
ran Desert where the participants could drive an authentic, military-grade
TOMCAR ATV through a bumpy and challenging off road path.
Tosoh Bioscience is the sole sponsor of this conference series and pro-
vides support for logistics and organization for the Scientific Committee.
The 11th HIC/RPC Bioseparation Conference will be organized by Tosoh
Bioscience GmbH and will take place in Switzerland in late winter/early
spring 2019.
