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.
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 Epstein-Barr virus BHRF1 covers amino acids 1-142. The expected molecular weight for the BHRF1 protein is calculated to be 19.8 kDa. This protein is generated in a e.coli-based system. The N-terminal 10xHis tag was smoothly integrated into the coding gene of BHRF1, which enables a simple process of detecting and purifying the BHRF1 recombinant protein in the following steps.
The Epstein-Barr virus (EBV) apoptosis regulator BHRF1 is a homolog of the cellular Bcl-2 protein, which plays a crucial role in regulating apoptosis and inhibiting the intrinsic apoptotic pathway. Similarly, BHRF1 functions as an anti-apoptotic protein in EBV-infected cells. By interacting with pro-apoptotic factors and preventing mitochondrial outer membrane permeabilization, BHRF1 helps the virus evade the host immune response and establish persistent infections. It is particularly involved in blocking the apoptotic response induced by various cellular stress signals, contributing to the survival of infected cells. Understanding the mechanisms employed by BHRF1 in modulating apoptosis is crucial for elucidating the pathogenesis of EBV-associated diseases and may have implications for the development of antiviral strategies.
