Primer Designing - (Apr/02/2015 )
Can anyone design primers for me for IFNG interferon, gamma
what do you need exactly?
Whats the sequence of your gene?

I need forward and reverse primers for amplification of needed gene,I need to calculate the specific temperature for these primers,
What do you need the amplification for? Sequencing? Real-time detection? ...?
How exactly did you try to design the primers, what did you use?
I need these primers for PCR. Also I need to select right restriction enzymes for these primers.
First of all I used ncbi to find my cDNA sequence. After that primer3 helped me to find primers. Then from a site which is called restriction mapper, I tried to find restriction enzymes.

So if I understand it completely: you want to amplify the gene (IFNG interferon, gamma) and add restriction sites to your primers?
Yes you understood completely.

ok
but what RE do you want to add?
I'll have a look later today to tell you how to design the general primers, then you already know that.
For the primers: since you need a specific gene there is no real "problem" here.
You simple have to use the first 18bps (or 21-24) of the gene for the forward primer + the RE (and linker) you want to add.
For the reverse: exact the same, but in the other direction.
Simple put, lets say this is your gene: TTTTTTTTTGGGGGGCCCCCAAAAGGGGGCCCCCC
You make the forward primer: TTTTTT
Reverse: GGGGG
(but in reality 18 bps long)
For the RE:
Forward:
XXXX-Linker-TTTTT
(from left to right 5'-3')
reverse:
YYYY-linker-GGGG
(from "right to left", 5'-3')
XXX = RE
YYY= RE
I have not had time to check it more in depth with your gene , but its the same approach...
