Chickens with a Truncated Light Chain Transgene Express Single-Domain H Chain-Only Antibodies.

H chain-only Igs are naturally produced in camelids and sharks. Because these Abs lack the L chain, the Ag-binding domain is half the size of a traditional Ab, allowing this type of Ig to bind to targets in novel ways. Consequently, the H chain-only single-domain Ab (sdAb) structure has the potential to increase the repertoire and functional range of an active humoral immune system.

The Identification and Heterologous Expression of the Biosynthetic Gene Cluster Encoding the Antibiotic and Anticancer Agent Marinomycin.

With the rise in antimicrobial resistance, there is an urgent need for new classes of antibiotic with which to treat infectious disease. Marinomycin, a polyene antibiotic from a marine microbe, has been shown capable of killing methicillin-resistant (MRSA) and vancomycin-resistant (VREF), as well as having promising activity against melanoma. An attractive solution to the photoprotection of this antibiotic has been demonstrated.
