Production of H-1PV Virus in NB-324K Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
H-1PV wild-type (wt) virus was produced in a 10-layer CellSTACK® (CS; Corning, Wiesbaden, Germany) according to Leuchs et al. 2016 (link). For this, NB-324K cells were seeded at 3.6E4 cells/cm2 and infected immediately with H-1PV wt (Kestler et al. 1999 (link)) at a multiplicity of infection (MOI) of 0.01 plaque forming units (PFU) per cell. To generate the clarified cell lysate, the cells were harvested after 4 days of incubation, lysed in 50 mM Tris-HCl (Trizma® hydrochloride; Sigma-Aldrich Co, St. Louis, USA) buffer, DNAse-treated (50 U/ml, Sigma-Aldrich Chemie GmbH, Steinheim, Germany), and filtered through 0.2- and 0.1-μm membranes (Sartorius AG, Göttingen, Germany).
The H-1PV is also publically available at ATCC® VR-356.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
