Latest highlights

CURRENT ISSUE

Using combinations of fluorescently labeled peptide–major histocompatability (pMHC) tetramers, two groups—Davis and colleagues, and Schumacher and colleagues—show that multiple T-cell populations with different antigen specificities can be monitored in parallel from small samples of human blood.


CURRENT ISSUE

Genome capture with PCR products
Brief Communication by Herman et al.

Seidman and colleagues use concatenated PCR products as subgenomic traps in this targeted genome capture technique. Subsequent high-throughput sequencing allows the detection of nucleotide and structural variations in the captured genomic regions.


CURRENT ISSUE

Digital profiling of microRNA

Correspondence by Linsen et al.

Next-generation sequencing is increasingly used for quantitative gene expression profiling. In this Correspondence, Cuppen and colleagues confirm its power for comparing relative expression differences, but state that absolute quantitation of small RNAs may be difficult because of library preparation biases.


CURRENT ISSUE

Finding relevant genes in RNAi screens

Correspondence by Kaplow et al.

In this Correspondence, Perrimon and colleagues introduce RNAiCut, an automated program that overlaps RNA interference results with protein-protein interaction data to identify thresholds above which genes are enriched for functions relevant to the screen.

Infrared fluorescent proteins

Fluorescent proteins: into the infrared
FREE

Researchers developed an infrared-emitting fluorescent protein from a bacterial phytochrome scaffold. This first member of a new class of imaging probes has advantages over visible-wavelength fluorescent proteins for in vivo imaging.


RESEARCH HIGHLIGHTS

Gene transfer through grafting

Grafting as a potent molecular tool
FREE

Grafted transgenic plants exchange large pieces of their DNA from both nuclear and chloroplast genomes at the immediate graft site. This intercellular gene transfer will yield clues about evolution and facilitate notoriously difficult chloroplast transformation.
