Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
The expression region of this recombinant Human ESR2 covers amino acids 2-323. This ESR2 protein is expected to have a theoretical molecular weight of 39.8 kDa. This protein is generated in a e.coli-based system. The ESR2 gene fragment has been modified by fusing the N-terminal 6xHis tag, providing convenience in detecting and purifying the recombinant ESR2 protein during the following stages.
Human estrogen receptor beta (ESR2) is a nuclear hormone receptor that plays a crucial role in mediating the physiological effects of estrogen. It is a member of the steroid hormone receptor superfamily and is expressed in various tissues, including the reproductive, cardiovascular, and central nervous systems. ESR2 functions as a transcription factor, regulating gene expression in response to estrogen binding. Its activation influences diverse processes such as cell proliferation, differentiation, and apoptosis. ESR2 is particularly involved in modulating the effects of estrogen in non-reproductive tissues. Research on ESR2 has implications for understanding hormone-dependent diseases, including certain cancers and exploring therapeutic interventions related to hormonal regulation.
