Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
ATXN2, or Ataxin-2, is a protein encoded by the ATXN2 gene, which is primarily associated with neurodegenerative diseases, particularly spinocerebellar ataxia type 2 (SCA2). Research into ATXN2 has gained significant attention due to its role in RNA metabolism, stress granule formation, and the pathogenesis of several neurodegenerative disorders. The protein is known to interact with various RNA-binding proteins and play a crucial role in cellular responses to stress, making it an important factor in the maintenance of neuronal health. Mutations or expansions in the polyglutamine (polyQ) region of ATXN2 are linked to SCA2, underscoring its relevance in the study of hereditary ataxias. Additionally, studies have suggested that ATXN2 may influence the progression of other neurodegenerative diseases such as ALS (amyotrophic lateral sclerosis) and Alzheimer's disease. The generation and study of recombinant ATXN2 proteins allow researchers to investigate the structural and functional properties of this protein, explore its interactions with other cellular components, and assess the impact of specific mutations. Understanding the biology of ATXN2 through recombinant protein studies is crucial for elucidating its role in disease mechanisms and may contribute to the development of targeted therapeutic strategies for conditions associated with ATXN2 dysfunction.
