绩效

先进的siRNA设计

QIAGEN在siRNA设计中的进步性,确保其高度创新且精良的HP OnGuard siRNA Design,能提供有效特异的siRNA。根据来自RNAi试验的数据建立极大容量的数据集,并在此基础上利用神经网络技术进行siRNAs设计,然后使用先进的、非冗余序列数据库和同源分析工具,检查该序列与同一基因组内其他序列的同源性。HP OnGuard siRNA Design具有许多独特先进的特性(见下表)。

神经网络技术使用BioPredsi神经网络设计siRNA,依托于极大的RNAi数据库。1-3
全球最大的siRNA验证项目该项目提供的数据使设计过程更完善,QIAGEN科学家已通过成千上万的siRNA确认其效能。该项目证实大量药用基因组siRNA功能至少有70%可被抑制。4

最新的siRNA靶序列NCBI数据库的最新数据确保设计的准确性。
不对称性对siRNA的设计基于5’端碱基对的不等稳定性,使得有义链被降解的同时,反义链在5’端的结合度降低而进入RISC。利用不对称性可制备高度可用的siRNA,且大大降低了错误链进入RISC而导致脱靶效应的风险。5,6

SNP位点屏蔽采用RefSNP数据库排除单核苷酸多态(SNP)的siRNA,由于这种siRNA有效性不同从而提高了siRNA的效果。
干扰素序列屏蔽屏蔽掉可导致干扰素反应的多重序列基序siRNA,弃用含有这种基序的siRNA。13,14

3' UTR/seed区域分析

研究表明siRNA反义链源区域与非目的靶标mRNA3’非编码区的匹配(见表),可能导致脱靶效应。siRNA双链的反义链上的2-7位是源区域,包括6个碱基。由于siRNA可模拟miRNA的作用,类似的匹配会促进非靶标mRNA的减少。使用QIAGEN设计的siRNA,与源自miRNA,siRNA和鼠RefSeq数据库的3’非编码区专利产品相配合,可对3’UTR/seed区进行分析研究。将每个siRNA与这些序列比对,检查任何可能导致miRNA类脱靶效应的同源序列。

siRNA源区域所有6个碱基与无关靶标3’非编码区序列完全匹配是常见情况,且无需除去这种siRNA。更罕见的是siRNA序列中出现源区域与10个或更多碱基同源匹配的情况,这种同源性很有可能导致脱靶效应,而这些siRNA可能因为与非靶标基因表现出更高的同源性而被弃用。

对于一些靶位点,很难选择到完全非同源性的siRNA。对于这种情况,非相关基因的EntrezGene ID可能是GeneGlobe提供的siRNA的非靶标基因。对这种类型同源性的关注并不意味这些基因一定会受到siRNA的影响,然而如有必要,后续分析中可以认定上述基因为潜在的非靶标基因。

常见问答

Which formats are available for FlexiPlate siRNA?

FlexiPlate siRNA is available in 3 different amounts: 0.1 nmol, 0.25 nmol, or 1 nmol per siRNA. Up to 4 human or mouse siRNAs can be selected per gene.

FlexiPlate siRNA is provided lyophilized in 96-well plates and is shipped at room temperature. siRNAs can be arranged in plates using the drag-and-drop tool at the GeneGlobe Web portal. Special formats are available on request: delivery in 384-well plates, delivery in solution and aliquoting.

 

FAQ-1358
How do I resuspend my FlexiPlate siRNAs?

FlexiPlate siRNAs are preannealed and dried down from a 10 µM solution in buffer. They should be resuspended in sterile RNase-free water only (you do not need siRNA buffer to resuspend the siRNAs).

To achieve a final siRNA stock concentration of 10 µM, resuspend:

  • 0.1 nmol siRNA in 10 µl
  • 0.25 nmol siRNA in 25 µl
  • 1 nmol siRNA in 100 µl

Mix gently and cover the plate with new sealing film. Allow siRNAs to dissolve for 30 minutes at 4°C with occasional shaking or gentle vortexing.

 

FAQ-1360
What is the composition of FlexiPlate siRNA buffer?

FlexiPlate siRNA buffer is 1x annealing buffer:

  • 30 mM HEPES (pH 7.4)

FAQ-1365
I have a Human Druggable Genome siRNA Set V2.0. Can I reorder the siRNAs from this set?

We have updated GeneGlobe and have exchanged several siRNAs with new designs. To find and order siRNAs from your set in GeneGlobe, search by using the siRNA catalog number (e.g., SI00000203). If you search by entering the gene name or accession number, only the new siRNA designs will be shown.

 

FAQ-1366
Can HP Validated siRNAs be ordered on the FlexiPlate?

Yes, you can order HP GenomeWide siRNAs and HP Validated siRNAs with the Flexiplate siRNA format. There is no price difference between HP GenomeWide siRNAs and HP Validated siRNAs ordered as FlexiPlate siRNA. For HP Validated siRNAs, no sequence information is provided.

 

FAQ-1367
Which controls can I choose for FlexiPlate siRNA?

You can add the following controls to your FlexiPlate siRNA plate: AllStars Negative Control siRNA, AllStars Cell Death Control siRNA, Negative Control siRNA, Human GAPDH siRNA, Human Beta-Actin siRNA, Human and mouse MAPK1 siRNA, Human or mouse Lamin A/C siRNA, Mouse AKT1 siRNA, or other siRNAs from GeneGlobe, such as HP Validated siRNAs.

FAQ-1368
Can I order Alexa Fluor labeled controls with FlexiPlate siRNA?

Labeled siRNAs must be ordered separately. They cannot be provided on the same plate with FlexiPlate siRNA.

 

FAQ-1369
If I cannot order FlexiPlate siRNA online, how do I order?

You can search for FlexiPlate siRNAs and design your plate layout online and then download it to an Excel file. Send the Excel file or the ID number of the Excel file to QIAGEN by fax or e-mail. Please also send the Word Flexiplate siRNA Order Form which includes shipping and billing information. Find out more about how to order if you cannot order online.

 

FAQ-1371
Can FlexiPlate siRNAs be ordered in plates other than the standard NUNC 96 well V bottom plates?

We do not provide FlexiPlate siRNAs in customer-specific plates for single plate orders. For large orders, there is the possibility to switch to other plates. Please inquire for details by contacting QIAGEN Technical Service.

 

FAQ-1458
Which kind of 96 and 384-well plates are available for FlexiPlate siRNAs?

FlexiPlate siRNAs will be supplied in NUNC Polystyrene V bottom plates.  NUNC Polystyrene plates can be ordered from Thermo Scientific Company.

  • Nunc MicroWell* 96-Well Microplates catalog # 249940.
  • Nunc* 384-Well Polystyrene Plates catalog # 265203.

http://www.thermoscientific.com/ecomm/servlet/home?storeId=11152&langId=-1

 

Other plates like ABgene AbGene Polypropylene plates can be used but ONLY upon request

FAQ-1459
What information is required to reorder specific siRNAs from a siRNA Set in FlexiPlate format?

Individual siRNAs from the QIAGEN HP siRNA Sets can be reordered in FlexiPlate format by entering the corresponding GeneGlobe catalog number (SI number) for the specific siRNA. SI number information for each siRNA is provided on the annotation CD which is included in the shipment of the siRNA Set.

FAQ-1463
What is the minimum number of siRNAs per order? If I order 40 siRNAs, can I get those on 2 plates?

The minimum order number is 36 in 96 well plates or on average 36 siRNAs per plate. The minimum average number of siRNAs per plate is 36. Thus, with 40 siRNAs, you would receive the siRNAs on one plate. For 72 siRNAs, you can split the siRNAs on 2 plates with 36 siRNA on each plate. If you order 150 siRNAs, you can for example get 3 plates with 50 siRNAs each.

 

To summarize: The minimum number of siRNAs for each catalog Number (or siRNA Sacle -1 nmol, 0.25 nmol or 0.1 nmol) is 36. Within a specific scale, plate can have less than 36 siRNAs, if the minimum average number of siRNAs per plate is 36 siRNAs.

FAQ-1468
Can different amounts of siRNA be ordered on one FlexiPlate?

Only one scale of siRNAs is available per FlexiPlate. If different scales are required, siRNAs have to be ordered on separate FlexiPlates. When ordering different scales on different plates, note that the average number of siRNAs per plate has to be a minimum of 36.

Please see FAQ 1370 for an example and further details.

FAQ-1473
Can FlexiPlate siRNA be ordered in solution on dry-ice?

We strongly recommend our standard method of shipment for FlexiPlate siRNAs in lyophilized form at room temperature. Delivery in solution on dry ice is possible as an exception only and has to be requested specifically when placing the order.

FAQ-1474
Are FlexiPlate siRNAs available at a higher final concentration than 10 µM?

We cannot provide FlexiPlate siRNAs at a higher final concentration. To obtain more concentrated siRNA solutions, individual lyophilized siRNAs can be resuspended in smaller amounts of sterile RNase-Free water. See FAQ 1360 for additional details on recommended resuspension volumes for various scales of FlexiPlate siRNA.

FAQ-1476
If FlexiPlate siRNA was accidentally redissolved in siRNA Suspension Buffer instead of water, resulting in a 2x buffer, would it affect performance of the siRNAs?

We do not expect a difference in performance of the siRNAs in case FlexiPlate siRNA was accidentally redissolved in siRNA Suspension Buffer. However, we have not tested this and do not have any proof data.

 

FAQ-1477
What are the turnaround times for FlexiPlate siRNA orders?

The standard turnaround time for FlexiPlate siRNA orders is 8 to 10 days. Turnaround times for special orders requiring pooling or aliquotting will differ, and will be communicated to the enduser upon ordering.

FAQ-1478
Can I still reorder siRNA that has been removed from the GeneGlobe data base?

Some siRNAs have been deleted from our standard GeneGlobe offering. For those siRNAs, the entries in public databases may have changed and the transcript is no longer listed in those databases. In other cases, we have added siRNAs with a new design.

You can still find previously listed siRNAs in GeneGlobe by searching for the specific SI number (ordering number). See also FAQ 1366 on this topic.
