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

Protein Description
DLL3 (Delta-like ligand 3) is a member of the Notch signaling pathway, primarily involved in cell differentiation and development. Its expression is notably restricted to certain neuroendocrine tumors, particularly small cell lung cancer (SCLC), making it a potential target for therapeutic interventions. Research has revealed that DLL3 acts as an oncofetal antigen, which is abundantly expressed in tumor cells while being minimally present in normal tissue. This unique expression pattern has prompted investigations into DLL3 as a biomarker for diagnosis and a target for targeted therapies, such as antibody-drug conjugates. Recombinant DLL3 protein has been essential for these studies, enabling the development of assays to measure DLL3 expression and facilitating the exploration of DLL3-targeted therapeutic strategies. Understanding the functional role of DLL3 in tumor biology and its potential implications in therapeutic context is crucial for advancing cancer treatment, especially for aggressive malignancies like SCLC. Therefore, ongoing research aims not only to elucidate the biological functions of DLL3 but also to evaluate its efficacy as a target for novel cancer therapies, including immunotherapy approaches, enhancing the hope for improved clinical outcomes in patients with DLL3-expressing tumors.
