Ask a question:
 

General Questions
How should I store my oligo and how long will it last?
How does IDT calculate oligo quantity as reported in my "spec" sheet?
How does IDT calculate the molecular weight for synthetic oligonucleotides?
How do I make double-stranded DNA?
How should I resuspend my dry oligo?

Ordering Oligos
I need an oligo that has a high percentage of "g" residues. Can you make that?
Can I make changes in my order once it has been sent?
What are the IUB codes for mixed bases?
I need a mixture of bases at one place in the oligo. How do I order this?

Oligo Purification
Do I have to purify 50-70 mer oligos used in arrays?
My protocol calls for "cartridge purified" (OPC)oligonucleotides. Do you offer that?
Are my oligos "salt free"?

Oligo Scale and Yield
Why don't you offer modifications on the 25 nmole scale synthesis?
How do I determine what scale synthesis I should order?
When is it appropriate to order the 25-nmole scale synthesis?
I ordered the 100 nmole scale, but I didn't get 100 nmoles of product. Why is that?

Molecular Biology Products, Kits and Methods
Are STARFIRE Probes different from standard oligonucleotide probes?
What is the STARFIRE Oligo labeling system?
Can STARFIRE Probes be used with my current hybridization protocol?
I am interested in RNAi's and siRNA's (interference RNA). Is this something that your company can help me with?

Other
Is the STARFIRE system a significant improvement over other oligo labeling methods?
