The Biochemistry & Molecular Biology Instrumentation (BMBI) module is an essential core resource to support the preparation and analysis of biological samples (RNA, DNA, and protein). Researchers are encouraged to seek assistance from the core director (Dr. Radu) or staff research associates to select the appropriate instruments for specific analysis, to schedule & properly use the instruments, and to obtain protocols to prepare the samples. Instrument/equipment is listed under three categories:
I. Basic instrumentations (centrifuges/rotors; incubators; freezers; PCR; etc)
II. Specialized spectrophotometers and protein dynamic analyzers
III. Highly-sensitive instruments for protein quantification and biochemical assays
Trained and authorized personnel may make reservations to use the facilities at https://uclajsei.bookmylab.com/
The BMBI core module resources consist of common instrumentations such as autoclaves, ultra-low temperature freezers, various centrifuges, incubators, an Alpha Innotech multi-imaging instrument, polymerase chain reaction (PCR) machines for DNA and RNA analysis (Bio-Rad Dual C1000 Thermal Cycler). Investigators can also determine gene expression profiles using high throughput microfluidic assays (BioMark Fluidigm Thermal Cycler), a next generation single cell RNA-sequencing (scRNA-seq) PCR approach.
