稳定性测试
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.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
运输条件
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
VISA (Virus-induced signaling adaptor) is a pivotal protein involved in the innate immune response, particularly in the detection of viral infections. When viruses invade host cells, they often manipulate intracellular signaling pathways to evade immune responses. VISA acts as an adaptor molecule that facilitates the activation of downstream signaling cascades, ultimately leading to the production of type I interferons (IFNs), which are crucial for antiviral defense. The study of VISA has gained significant attention due to its role in mediating the host's immune response to diverse pathogens, including RNA viruses like influenza and various coronaviruses. Dysregulation of VISA signaling can result in impaired immune responses or excessive inflammation, contributing to disease pathology. Therefore, a detailed understanding of VISA structure and function, including the identification of its interaction partners and post-translational modifications, is essential for developing therapeutic strategies aimed at enhancing antiviral immunity or ameliorating autoimmune diseases. Recent advances in structural biology and biochemistry have provided insights into the mechanisms of VISA activation and its role in immune signaling, laying the groundwork for potential drug development and vaccine strategies that harness the body’s natural defense mechanisms against viral threats. Further research into VISA's functions could unravel novel therapeutic targets and enhance our understanding of host-pathogen interactions at a molecular level.
