Novus' Pyruvate Kinase M2 antibody (cat # NBP1-48308) has received some glowing product reviews and customer feedback lately. One satisfied customer wrote, "The best thing about this antibody is that it works well for immunofluorescence staining of frozen sections of rat glioblastoma tumor samples... [The staining] is exactly what we expected. This result further confirms that the antibody is specific for PKM2, and not PKM1."
