From 4 Days
GenCefe provides custom siRNA synthesis for targeted gene-silencing research, supporting standard and modified siRNA oligos for different experimental requirements. Depending on the project, researchers can provide their own sequences or work with our team on siRNA design before synthesis.
Our custom siRNA synthesis service supports different sequence and modification requirements, as well as flexible synthesis scales. Available options include custom target siRNA, NC siRNA, NC FAM siRNA, and positive-control siRNA products for different experimental setups.
Key Features:
Custom siRNA Design: Support siRNA design and custom synthesis from nmol to gram level, with options tailored to target sequences and project requirements.
Standard and Modified Options: Provide standard and modified siRNA oligos with customization for sequence and chemical modification requirements.
Fast Turnaround: Offer rapid production for applicable projects, with turnaround times starting from 4 days depending on sequence, modification, scale, and purification requirements.
Quality Management: siRNA production is supported by ISO 9001 and ISO 13485 certified quality management systems, with QC performed according to project specifications.
