USA - custom petides?

[avinash]

Hi All,

I'm a first year grad student just starting in the lab.

Need to order some custom peptides for my project, and would like to know what vendors you use. There seem to be tons of companies out there advertising their services, but do not know whom to trust.

Any help will be appreciated. Many thanks
Avinash

Pls try our GL Biochem. We made 10,000 peptides every month.
Most of US custom peptide is supplied by us.

Genscript was good. I only have used them once though.

[avinash]

Excellent.

We decided to order peptides from them too. We'd used their services for oligos sometime back, but the kicker was their offer of a 20% discount!

Many thanks,
Avinash

Dear Avinash,

I admited GenScript was good. They are my friends too.
So hope you can satify with this service.

You may see my [Only registered users see links. ] to know much more about us.
