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.
-
Shipping
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
STARD4, or Steroidogenic Acute Regulatory Protein 4, is a member of the STARD family of proteins, which are crucial for the transport of lipophilic molecules, particularly steroids, across cellular membranes. Its primary role involves mediating the delivery of cholesterol to mitochondria, where steroidogenesis begins. The interest in STARD4 has surged in recent years due to its potential implications in various physiological and pathological processes, including reproductive function, hormone modulation, and metabolic diseases. Dysregulation of STARD4 has been linked to conditions such as polycystic ovary syndrome (PCOS) and certain types of cancer, making it a target for therapeutic research. The study of STARD4 recombinant proteins provides insights into its structure-function relationships, interactions with other cellular components, and the molecular mechanisms underlying its activity. Additionally, investigating STARD4 can help refine our understanding of steroid hormone biosynthesis and its impact on health and disease, ultimately paving the way for innovative treatments. The development of STARD4 recombinant proteins also opens avenues for exploring its potential in biotechnology and pharmacology, emphasizing the importance of continuing research in this field.
