The lab

We share this lab with Dr, Xavier Soberon, Director of the Institute. Our groups have common interest in molecular evolution of proteins and catalysis.
The laboratory has 16 individual working benches, each one with a desk, and several meters of lateral benches. Aditionally, the lab has five offices, three rooms for comun equipment, a lab dedicated to work with radioisotops, and a large bench with computers. The Institute has several floor centrifuges, ultracentrifuges, cold rooms, temperature-controlled rooms, a DNA synthesis unit, a polypeptide synthesis unit, an animal house, electron and confocal microscopy facilities, dark room, central computing unit for institutional service, etc.
The major equipment includes digital gel recording set, spectrograph, spin vacum dryers, fume cave, steril benches, several thermocyclers, ultrafreecers, autoclave, HPLC, automatic DNA sequencing aparatus, several power packs, electroporators, incubators temperature-controlled baths, analytical balances, sonicator, refrigerated bench centrifugues, microwave ovens,several electrophoresis chambers, etc. We have several Macs, PC's and Silicon Graphyc computers.

Group Members

Lety. She controls everybody and everything in the lab.
Mary, she is in charge of preparing samples for automatic sequencing and collaborates in directed evolution projects.
Here she is reading about reptiles, her most profound interest in life.
Ricardo finished his Ph D last July and continued in the group now as research staff.
Ricardo. It´s hard to see when he is working.
Isa, She was visiting the group. She comes from Alicante University, Spain. She plans to come again soon! (esa cara de espanto no es la mas usual!!)
Isa, from Choni´s Lab.
He is Angel Ernesto. He is from Cuba and he is doing his Ph D here.
Rene Hernandez. This guy is in control of our DNA Sequencer.
