Premium

Version 1.2.6 of CAMERA is available here. The new version includes six new publicly available metagenomic datasets, including the Mediterranean gutless worm metagenome, the acid mine drainage metagenome, and the Waseca county farm soil metagenome. The database also includes a new annotation pipeline, improved navigation, improved Blast services, and an enhanced fragment recruitment viewer.
 

 
Biomatrica has introduced PCRboost, a reagent that enhances PCR and RT-PCR amplification of difficult samples. Researchers replace the water in the reaction with PCRboost to improve amplification of trace samples of less than or equal to 1 nanogram, degraded samples, low-copy transcripts, multiplexing, and samples containing inhibitory factors.
