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.

Protein Description
Haptoglobin is a crucial plasma protein that binds free hemoglobin released during hemolysis, preventing its oxidative damage and facilitating its clearance by macrophages. This protein exists in various genetic polymorphisms, with distinct isoforms exhibiting different functional properties. The study of recombinant haptoglobin has gained prominence due to its potential therapeutic applications in conditions such as hemolytic anemia, sepsis, and chronic inflammatory diseases, where free hemoglobin levels are elevated. Advancements in recombinant DNA technology have enabled the production of haptoglobin isoforms with controlled properties, allowing researchers to investigate their specific roles in oxidative stress responses and immune modulation. Furthermore, the characterization of recombinant haptoglobin can provide insights into its protective mechanisms against kidney injury and organ dysfunction related to hemolysis. High-throughput screening and structural studies of these isoforms may reveal new avenues for drug development. As such, the study of recombinant haptoglobin not only enhances our understanding of its biological function but also holds promise for innovative therapeutic strategies targeting diseases associated with hemolysis and oxidative damage.
