High Five cells
High Five (BTI-Tn-5B1-4) is an insect

High Five cells have become one of the most commonly used cell lines for recombinant protein expression using
baculovirus or transfection, and have been demonstrated to express more recombinant protein than other lepidopteran cell lines, such as Sf9 cells.[2][3][4][5][6][7][8] The High Five cells have been used to produce the VLP-based HPV vaccine Cervarix.[9]
They can be grown in the absence of serum, and can be cultured in a loose attached state or in suspension[10] High Five cells produce abundant microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), making it suitable to study all three types of small silencing RNAs.[11]
The High Five cell line, like other cell lines,[12] has been found to host a non-pathogenic adventitious alphanodavirus. Researchers at the Boyce Thompson Institute were able to isolate virus-free sub-clones, named Tnao38[13][14] and Tnms42.[15]
