Homemade RealTime Syb-GreenI-Mix - (Jan/27/2006 )
As KR suggested:
http://www.cif.ucr.edu/Assets/QPCR/QPCRmix.pdf
has a good report on it.
I use Applied Biosystems mater mix. As they need to label all the harzardous ingredients in the mix they have mantioned CAS numbers for DMSO and Tween20. I dont know the exact concentrations in the comercial preparations but upto 10% DMSO has been used in regular PCRs to increase the product yield and efficeincy.
In the paper above, I read that SYBR green dye should stable be in 10mM Tris pH 7.5 and frozen in small aliquots.
Cheers
i our lab we developed and standardise a homemade sybr green mix. its efficency is comparable with the commersiable sybr green mix. But need few changes according to your experimental need.
i am attached the mix...
if any body need further clarification
Here's a short tech report from Biotechniques: Hope it helps. I'm trying to move from Taqman to Sybr Green I since it's much cheaper, and my PCR is optimized.

hi,thank u very much.in our lab,we used the homemade sybr green I in real-time PCR to cut the costs ,we just diluted the dye in TE to 10X for stock in -20C ,when we did qPCR, we just diluted the stock solution to 1X in an usual PCR mixture( including template,buffer,primers,taq polymerase,dNTPs),which seemed not to be precise now.

best regards
