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
SIAE (Sialic Acid Acetylesterase) is an enzyme implicated in the regulation of sialylation, a critical post-translational modification that influences cellular interactions, signaling, and immune responses. Research has demonstrated that SIAE plays a crucial role in modulating the immune system by removing sialic acid residues from glycoproteins and glycolipids, thereby affecting the recognition and clearance of pathogens and apoptotic cells. Dysregulation of SIAE activity has been linked to various diseases, including autoimmune disorders and cancer, where altered sialylation patterns can lead to immune evasion and tumor progression. The study of SIAE recombinant proteins has gained traction due to their potential applications in therapeutic development and as biomarkers for disease diagnosis. By producing SIAE in recombinant form, researchers can investigate its structure-function relationships, enzymatic mechanisms, and interaction with sialylated substrates. This research not only enhances our understanding of SIAE's biological functions but also paves the way for novel interventions targeting sialylation pathways in disease states. Overall, the investigation of SIAE recombinant proteins offers valuable insights into cellular biology and the development of strategies to manipulate the sialylation process for therapeutic benefit.
