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
SIRP alpha (Signal Regulatory Protein alpha), also known as CD172a, plays a critical role in regulating immune responses by interacting with the CD47 molecule, which is often referred to as the "don't eat me" signal. This interaction inhibits phagocytosis by macrophages and is crucial for maintaining self-tolerance and preventing autoimmunity. The study of SIRP alpha/CD172a recombinant proteins has gained prominence due to its potential therapeutic implications in cancer immunotherapy and autoimmune diseases. In tumors, cancer cells often overexpress CD47, allowing them to evade immune detection and destruction. By engineering SIRP alpha as a recombinant protein, researchers can block the CD47-SIRP alpha interaction, enhancing phagocytosis of cancer cells by macrophages and promoting anti-tumor immunity. Additionally, SIRP alpha/CD172a protein research provides insights into the mechanisms of immune regulation and has implications for designing novel immunotherapeutic strategies. The development of SIRP alpha/CD172a recombinant protein not only advances our understanding of immune checkpoint pathways but also opens new avenues for clinical applications in treating various malignancies and enhancing the effectiveness of existing immunotherapies. Moreover, the study of this protein contributes to a broader understanding of the immune system's regulation, potentially leading to breakthroughs in managing immune-related disorders.
