Are there commercially available mRNA purification kits designed for various organisms?

Yes, commercially available mRNA purification kits are often designed for various organisms including mammals, bacteria, and yeast. For example, bacterial mRNA purification kits are specifically designed for isolating mRNA from bacteria like E. coli and other bacterial species. Yeast mRNA purification kits are used for yeast organisms like Candida. Mammalian mRNA purification kits are designed for animal and human tissues or cell lines and are designed to handle complex samples with high levels of rRNA and other cellular components.
