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.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

Target Background

Inhibitor of DNA replication that promotes cell death in response to DNA damage. Acts as a guardian of the genome by killing cells with defective replication. Persistently blocks stressed replication forks by opening chromatin across replication initiation sites at stressed replication forks, possibly leading to unwind DNA ahead of the MCM helicase and block fork progression, ultimately leading to cell death. Acts independently of ATR. Also acts as an interferon (IFN)-induced antiviral protein which acts as an inhibitor of retrovirus protein synthesis. Specifically abrogates the production of retroviruses such as human immunodeficiency virus 1 (HIV-1) by acting as a specific inhibitor of the synthesis of retroviruses encoded proteins in a codon-usage-dependent manner. Binds to tRNAs and exploits the unique viral codon bias towards A/T nucleotides. The exact inhibition mechanism is unclear: may either sequester tRNAs, prevent their maturation via post-transcriptional processing or may accelerate their deacylation. Does not inhibit reverse transcription, integration or production and nuclear export of viral RNA.

  2. SLFN11 is frequently methylated in human colorectal cancer, and the expression of SLFN11 is regulated by promoter region methylation. Methylation of SLFN11 reduced the sensitivity of CRC cells to cisplatin. PMID: 28403629
  3. SLFN11 is a relevant predictive biomarker of sensitivity to PARP inhibitor monotherapy in SCLC and we identify combinatorial therapy with TMZ as a particularly promising therapeutic strategy that warrants further clinical investigation PMID: 27440269
  4. DNA methylation at SLFN11 cg10911913 was positively associated with measured levels of all 3 PM2.5 species. PMID: 27982729
  5. In vivo silencing of SLFN11 was associated with marked deposition of H3K27me3, a histone modification placed by EZH2, within the gene body of SLFN11, inducing local chromatin condensation and gene silencing. PMID: 28196596
  6. the results identify SLFN11 epigenetic inactivation as a predictor of resistance to platinum drugs in human cancer. PMID: 26625211
  7. SLFN11 inhibits checkpoint maintenance and homologous recombination repair by promoting the destabilization of the RPA-ssDNA complex, thereby sensitizing cancer cell lines expressing high endogenous levels of SLFN11 to DNA-damaging agents. PMID: 26658330
  8. SLFN11 has a role as a transcriptional target of EWS-FLI1 and is a determinant of drug response in Ewing sarcoma PMID: 25779942

  10. SLFN11 selectively inhibits viral protein synthesis in HIV-infected cells by means of codon-bias discrimination PMID: 23000900
  11. SLFN11 expression is causally associated with the activity of DNA-damaging agents in cancer cells, and has a broad expression range in colon and ovarian adenocarcinomas. PMID: 22927417
