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
ESAT-6 (Early Secreted Antigenic Target 6) is a 6-kDa protein produced by pathogenic strains of Mycobacterium tuberculosis, the causative agent of tuberculosis (TB). Its significance lies in its key role in the immune response, as it is recognized by T cells in infected individuals, making it a potential biomarker for TB diagnosis. Research into ESAT-6 has gained momentum due to its promising application in the development of vaccines and diagnostic tools. The protein is part of a family of virulence factors secreted by the Type VII secretion system, which plays a critical role in mycobacterial pathogenesis. Understanding the structure and function of ESAT-6 and its interactions with host immune cells is crucial for unraveling the mechanisms of TB infection and disease progression. Moreover, recombinant ESAT-6 proteins are being studied for their potential use in immunological assays, such as the QuantiFERON-TB Gold test, which helps differentiate between active and latent TB infections. The ongoing research on ESAT-6 encompasses various fields, including immunology, molecular biology, and vaccine development, aiming to enhance TB control strategies and improve global health outcomes. As TB remains a major public health challenge worldwide, the exploration of ESAT-6 as a recombinant protein provides a promising avenue for innovative approaches to diagnosis, treatment, and prevention.
