B-Bridge International s siSolutions, Ambion s siPort NeoFx, and Genisphere s Array 900miRNA Kits


B-Bridge International said that it has released its siSolutions line of RNAi products, including custom siRNAs, in Japan.

The company said the products would be made available in North America in the beginning of December.

Ambion has recently introduced the siPort NeoFx transfection agent.

The company said the product’s lipid-based formulation can be used to efficiently transfect adherent cells with siRNAs as they are subcultured without increased cytotoxicity.

The agent, Ambion noted, can be used to deliver siRNAs into many cell types, including MCF-7 (human breast adenocarcinoma), HT-29 (human colorectal adenocarcinoma), HeLa-S3 (human cervix adenocarcinoma), HeLa (human cervix adenocarcinoma), HEP-G2 (human hepatocellular carcinoma), BJ (human foreskin fibroblast), A549 (human lung carcinoma), UMR106 (rat osteosarcoma), SKOv3 (human ovarian carcinoma), and SKNAS (human bone marrow neuroblastoma).

Genisphere has recently introduced its Array 900miRNA kits.

According to the company, the kits are microarray labeling kits specifically designed for use with microRNAs, siRNAs, and other small RNA molecules such as nuclease fragments.

The kits provide validated results from only 50 to 200 nanograms of microRNA-enriched samples, said Genisphere.
