Off the shelf

Primers & Probes PCR, sequencing, cloning and qPCR, including dual-labeled and double-quenched hydrolysis probes. miRNA Mimics, inhibitors and matched negative controls across the miRBase catalogue. CRISPR Guides crRNA, tracrRNA and non-targeting controls, chemically synthesised. RNAi & RNA siRNA duplexes, modified RNA oligos and matched controls.

Made to order

Gene Synthesis Whole genes synthesised and cloned into the vector you name, delivered as a sequence-verified construct. Quoted per project. PCR Products Linear double-stranded DNA to your exact sequence — no cloning, no vector. Made to length. NGS Oligos & Pools Adapter and index primers, hybridisation-capture probes and multiplex PCR panels — single tubes or pools of 3 to 10,000 oligos. Quoted per project. IVD-grade Oligos Diagnostic-grade primers, hydrolysis probes and double-quenched probes, made in a cleanroom to a tightened specification. Quoted per project.

Specimen. This is what a released record looks like. The order, the sequences and every number on it are made up for the purpose of showing the format — the sequence used is the public M13 forward primer, not anyone's order. Look up a real order.
