The American Society of Gene & Cell Therapy (ASGCT) held their 22nd annual meeting in Washington D.C. last week from April 29th through May 2nd bringing together a record number of over 3,400 attendees to share and discuss the remarkable work going on to advance this field. With 23 Scientific Symposia and 1000 abstracts presented through talks and poster sessions over the course of the conference, there was no shortage of knowledge to be shared.

Enhanced liquid-phase stability of live-attenuated Flavivirus vaccines using recombinant albumin
The single-stranded RNA viruses belonging to the genus Flavivirus (family, Flaviviridae) are significant to global public health due to the high rates of morbidity and mortality they cause.1 For example, Yellow Fever sickens approximately 200,000 people and kills 30,000 annually.2 Other viruses belonging to this genus include the mosquito-borne diseases Dengue Fever, Japanese encephalitis, West Nile virus, and Zika virus, and the tick-borne diseases Tick-borne Encephalitis, Kyasanur Forest Disease, Alkhurma disease, and Omsk hemorrhagic fever.
Expand virus-producing cells to desired confluency. Remove growth medium and add the desired virus to be expanded (virus or plasmid DNA). Add Cellastim S (Product Number: 777HSA017S) to the expression media and allow virus to propagate. Harvest culture and determine virus titer by preferred method.
Virus Production Using VERO Cells with Microcarriers Without Serum in Chemically Defined Cell Culture Media

Combine supplements of OptiVERO. Prepare complementary reagents. Wash cells to remove traces of FBS and harvest from growth surface. Seed in OptiVERO and expand in cell culture flasks for at least 3 passages to allow for adaptation. Prepare microcarrier system, inoculate with VERO cells, and incubate 3-4 days for adhesion and expansion. Add virus of interest in minimal basal MEM. Incubate for 2 hours at 37°C. Add fresh OptiVERO. Allow virus expansion for 3-13 days. Quantify virus by desired method.
