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
COBRA1, also known as CTCF-Dependent, RNA-Binding Protein 1, is a crucial component in the regulation of gene expression and chromatin structure. Research into COBRA1 has gained momentum due to its significant role in various cellular processes, including transcriptional regulation and RNA processing. This protein is particularly important in the context of cancer biology, as dysregulation of COBRA1 has been linked to tumorigenesis and metastasis. Studies have shown that COBRA1 interacts with various transcription factors and chromatin remodelers, indicating its involvement in the establishment and maintenance of higher-order chromatin structures. Furthermore, COBRA1 has been implicated in the regulation of alternative splicing and mRNA stability, adding another layer to its functional repertoire in gene expression regulation. Understanding the mechanisms by which COBRA1 operates can provide insights into its potential as a therapeutic target in cancer treatment and other diseases characterized by gene expression dysregulation. Current research focuses on elucidating the molecular pathways involving COBRA1, exploring its protein interactions, and assessing its impact on cellular phenotypes. These insights aim to advance our understanding of COBRA1's contributions to health and disease, making it a promising candidate for further exploration in both basic and clinical research settings.
