Utilizing ENU mutagenesis. we identified a mutant mouse with elevated platelets. Genetic mapping localized the mutation to an interval on chromosome 19 that encodes the Jak2 tyrosine kinase. We identified a A3056T mutation resulting in a premature stop codon within exon 19 of Jak2 (Jak2(K915X)). https://parisnaturalfoodes.shop/product-category/glossy-lipstick-nude-mist-503/
