Tag Info

Tag type will be determined during the manufacturing process.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Form

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 before Lyophilization

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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein FAQs

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

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function

Catalyzes the formation of 25-hydroxycholesterol from cholesterol, leading to repress cholesterol biosynthetic enzymes. Plays a key role in cell positioning and movement in lymphoid tissues: 25-hydroxycholesterol is an intermediate in biosynthesis of 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC), an oxysterol that acts as a ligand for the G protein-coupled receptor GPR183/EBI2, a chemotactic receptor for a number of lymphoid cells. May play an important role in regulating lipid metabolism by synthesizing a corepressor that blocks sterol regulatory element binding protein (SREBP) processing. As an interferon-stimulated gene, has broad antiviral activities against a wide range of enveloped viruses, such as vesicular stomatitis virus (VSV) and SARS coronavirus-2 (SARS-CoV-2). Its product, 25-hydroxycholesterol, activates the ER-localized enzyme ACAT to induce internalization of accessible cholesterol on the plasma membrane and restricts SARS-CoV-2 S protein-mediated fusion which inhibits virus replication. In testis, production of 25-hydroxycholesterol by macrophages plays a role in Leydig cell differentiation.

Gene References into Functions

We examined whether 25HC restricts infection by mammalian reovirus. Results suggest that 25HC inhibits the efficiency of cellular entry of reovirus virions, which may require specific endosomal membrane dynamics for efficient membrane penetration. PMID: 29950420
We detected Cholesterol 25-hydroxylase, the enzyme responsible for 25-HC production, in human spermatozoa at the level of the neck and the post acrosomal area. Upon incubation with spermatozoa, 25-HC induced calcium and cholesterol transients in connection with the acrosomal reaction. PMID: 27912195
Exome analysis in 212 multiple sclerosis and 14 neuromyelitis optica patients identified a rare CH25H p.Q17H mutation in two NMO patients of Asian ancestry. In addition, association analysis of common CH25H variants. PMID: 26857497
Infection with HCV causes up-regulation of interferon-inducible CH25H in vivo. PMID: 25999047
These results demonstrate that CH25H constitutes a primary innate response against hepatitis C virus infection through regulating host lipid metabolism. PMID: 25903345
Cholesterol 25-hydroxylase production by dendritic cells and macrophages is regulated by type I interferons. PMID: 20699362
Based on the results of genome-wide screens, along with biological studies, we selected three genes as candidates for AD risk factors: ATP-binding cassette transporter A1 (ABCA1), cholesterol 25-hydroxylase (CH25H) and cholesterol 24-hydroxylase (CH24H). PMID: 16157450
