Stability Test
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.
-
Storage & Shelf Life
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
RBP4, or retinol-binding protein 4, is a protein that plays a crucial role in vitamin A transport and metabolism in the human body. Its primary function is to bind retinol, the alcohol form of vitamin A, and facilitate its delivery to tissues, thereby contributing to various physiological functions, including vision, immune response, and skin health. Recent research has highlighted RBP4's potential involvement in metabolic disorders, such as obesity and type 2 diabetes, as elevated levels of RBP4 in the bloodstream have been correlated with insulin resistance and dyslipidemia. Given its significance in these metabolic pathways, RBP4 has emerged as a potential biomarker for assessing metabolic health and as a target for therapeutic interventions. The production of recombinant RBP4 proteins has become critical for advancing research into its structure-function relationship, elucidating its biological roles, and exploring its implications in diseases. By utilizing recombinant DNA technology, researchers can produce RBP4 in sufficient quantities for various assays, enabling in-depth studies of its interactions with retinol and other cellular components. This research is expected to yield insights that could inform the development of novel strategies for diagnosing and treating metabolic disorders linked to RBP4 dysregulation. Overall, the study of recombinant RBP4 proteins is a promising avenue that bridges the gap between basic science and clinical application, enhancing our understanding of vitamin A metabolism and its impact on human health.
