Delivery of my package was delayed and my Edit-R Cas9 Nuclease Expression plasmid, mKate2 Transfection Optimization plasmid, tracrRNA and/or crRNAs have been at room temperature for a week. Are they OK to use?

Samples are shipped as a dried pellet and are stable for two to four weeks at room temperature. All RNA oligonucleotides and plasmid DNA should be placed at -20 �C or -80 �C upon receipt.
