Can you make xGen Lockdown Probes based on our design results from another vendor?

Generally speaking, all IDT needs are the capture probe sequences to synthesize xGen Lockdown Probes. For custom designs, it is important to note that other vendors may use different databases for target sequence extraction. For reference, IDT uses NCBI databases (at the end of 2013 we were using RefSeq Build 58).
