Ambion s siPort and Mirus TransIt-siQuest


Ambion has just released the siPort siRNA electroporation buffer, which is used for the delivery of siRNAs to primary and difficult-to-transfect cells, according to the company.

The buffer, Ambion said, can be used with multiple types of electroporators to ensure highly efficient delivery of siRNA into cells while maintaining high cell viability.

Mirus has recently introduced its TransIt-siQuest siRNA transfection kit.

The kit, said the company, enables highly efficient siRNA transfection in mammalian cells with significantly reduced levels of cell damage as compared to cationic-liposome based transfection reagents.

Mirus also notes that transfections with the kit are most effective when carried out in complete growth media, with no media change or serum addition required.
