Novel method of paraffin embedding cultured cells and organoids using silicone molds.

One of the main methods of antibody validation is testing on positive and negative control tissues with known expression levels of a given antigen. However, this approach is reliant on availability of tissues and reliable protein expression datasets, which are not always available.
