We have conducted much research and used molecular biology approaches extensively, including cloning, site-directed mutagenesis, PCR of GC-rich and secondary structure targets, long PCR, fast PCR, high fidelity PCR, library construction, antibody engineering. See our a partial list of publications below.

We offer the following MLase(TM) certified molecular biology service items.

1. PCR: difficult templates (GC-rich, secondary structures, high AT), long PCR, high-fidelity PCR, fast PCR, large number of templates, miRNA and other RNA reverse transcription PCR etc.

2. Cloning: PCR products, restriction endonuclease fragments, synthetic DNA constructs into cloning vectors and expression vectors for E. coli, yeast, insect and mammalian expression.

3. Site-directed mutagenesis: point mutation, deletion and insertion mutation, multiple mutations, long inserts, GC-rich or simply difficult constructs

4. Library construction: we have producted large-repertoire libraries utilizing our optimized cloning, and competent cells, and transformation approaches.

5. Protein expression and purification: we can express and over-express your gene of interest in any of your expression systems of choice. We can also purify proteins and deliver the protein you need that meets your specifications.

6. Your other  biology needs-including sequencing, troubleshooting, advice on cloning strategy, design, codon optimization, and ELISA etc.

You let us know what you need done by when and in what cost constraints, we will do our best to deliver the product or the data according to the specifications. If we do not deliver it, we will let you know ASAP and you do not pay!
