Our Services

Full Length cDNA Library (Rice roots)

Following full-length cDNA libraries derived from roots of three-week-old rice plant grown under normal hydroponic conditions. cDNA populations were normalized, fractionated and pooled in two size ranges (0.5-2.0 kb and 2.0-6.0 kb).

Full Length cDNA Clones (Rice roots)

following clones with GenBank acc. no. were isolated from the Full-Length cDNA Library. cDNA was inserted into the vector pYEXP7 for functional expression of the rice cDNA in yeast (Sc) cells.

Screening of Plant Functional Gene

This service will help customers to isolate/identify a functional plant (e.g. rice) gene(s) by either yeast complementation-based screening of our cDNA library or molecular cloning from the cDNA library.

Protein Interaction Assay

In this service we will apply the “Split-Ubiquitin Yeast Two Hybrid System” to test protein-protein interaction(s) of customer’s interest.
