Ten years ago, scientists put DNA barcodes in AAV vectors, creating an approach that simplified, expedited, and streamlined AAV screening. 

With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

A combinatorial approach enabled high-throughput screening of protein libraries for desired target binding.

This month marks the 100-year anniversary of BCG, still the only approved vaccine against the lethal pathogen. But there are new vaccines for this wily foe on the horizon.

(A-E) represent cells containing HAT-tagged proteins stained with the DNA dye, DAPI, and a monoclonal antibody against hemagluttinin, α-HA. At right the images are merged. (F-J) indicates cells carrying V5 tagged proteins. The bar equals 2 μm.Aliens sifting through the remains of a lost human civilization might puzzle over the function of a ladle. But if found in a room associate

Selling Systems Biology Can this still-unproven (and much-hyped) field revolutionize drug discovery? By Brendan Borrell ARTICLE EXTRAS 1,2 suggested that the drug works primarily in patients with mutations in the ErbB1 epidermal growth factor receptor. The inner workings of the ErbB receptor family, with its sprawling pathways and multiple phosphatases, had long been a headache for drug makers. That complexity showed itself in this instance, too - sometimes the drug wa

This is a 20 kb region surrounding exon 2 of the MET gene. Gap-free alignable segments are represented as horizontal lines along the human reference sequence; the line's height represents the identity of that alignment. Aristotle envisioned humanity as the pinnacle of a "Great Chai
