Product Overview

Tag	N/A
Host Species	Human
Synonym	Adropin, Energy homeostasis-associated protein, ENHO, C9orf165, UNQ470.
Background	Energy Homeostasis Associated (ENHO) participates in glucose homeostasis maintenance and lipid metabolism. ENHO is expressed in the liver and the brain. The role of ENHO in obesity or diabetes is studied.
Description	ENHO Human Recombinant expressed in E.Coli is a single, non-glycosylated, polypeptide chain (a.a 34-76) containing 121a.a. including extra 78 N-terminala.a.. The total molecular weight is 13.05kDa (calculated).
Source	E.coli
AA Sequence	MGGKSNGEKK YIVGFKQGFK SCAKKEDVIS EKGGKLQKCF KYVDAASATL NEKAVEELKK DPSVAYVEED KLFKALTSCHSRSADVDSLS ESSPNSSPGP CPEKAPPPQK PSHEGSYLLQ P.
Purity	>90.0% as determined by SDS-PAGE.
Endotoxin	<1.0 EU per μg by the LAL method.
Formulation	ENHO filtered (0.4 µm) and lyophilized from 0.5mg/ml in phosphate buffered saline.
Stability	Recombinant protein is stable for 12 months at -70°C
Usage	For Research Use Only
Storage	Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
