Invitrogen this week announced the launch of Stempro MSC SFM, a serum-free media designed specifically to culture mesenchymal stem cells.
 
STEMPRO MSC SFM is completely defined and maintains MSCs in an undifferentiated state for more than nine passages.
 
 Invitrogen has also launched Stempro Adipogenesis and Stempro Osteogenesis differentiation kits. These kits contain media and specific supplements that can induce MSCs to differentiate into adipocytes and osteocytes.
 

 
Guava Technologies recently announced the launch of a new package for CD4 monitoring. Comprising an integrated package of reagents, software, and instrumentation, the Guava Auto CD4/CD4% system was designed to provide developing countries with a tool to help fight the global AIDS pandemic.
 
By providing values for both CD4 and CD4% of total lymphocytes, the assay is applicable to both adult and pediatric samples.
 
The Guava Auto CD4/CD4% assay comes with a reagent kit and provides CD4 counts, total lymphocyte counts, and CD4% values in one assay. The new assay employs a premade cocktail and 10 µL of whole blood in a two-step, no-wash protocol.
 

 
Advalytix, a product group within Olympus Life Science Research Europa, recently introduced the CellEvator mixer, which uses proprietary surface acoustic wave mixing technology to enhance sample mixing during cell sorting. The CellEvator is a drop-in replacement for the built-in mechanical sample mixer in Becton Dickinson’s FACSAria cell-sorting system.
 
CellEvator induces surface waves into the sample from the bottom of the sample tube, preventing cells from settling and reducing the likelihood of cell adhesion. The technology is non-invasive and has no moving parts, allowing virtually maintenance-free operation, Advalytix said. And, unlike vortex mixing, SAW creates no air bubbles and mixes in a vertical direction. CellEvator is programmable to vary mixing intensity, as well as the length of an initial mixing burst. 
 

 
Agilent Technologies subsidiary Velocity11 has launched automated workstations for bulk reagent /cell dispensing applications, the company announced recently.
 
The R-Series BenchCel features a high-speed plate shuttle that enables rapid accessing of integrated microplate stacks and peripheral instruments. Even the smallest R-Series BenchCel can support three peripheral instruments, allowing customers to configure workstations that combine a broad range of functionality, including barcode labeling, microplate sealing, plate reading, and centrifugation, as well as liquid handling using Velocity11 or third-party peripherals, the company said.
 
Users can choose from 2-, 4-, or 6-stack instrument configurations, and from four different sizes of removable racks with capacities of 15 to 70 standard microplates. A delidding function removes and replaces microplate lids as necessary. The R-Series BenchCel is powered by Velocity11's automation and control software with a scheduler that includes a robot device diagnostics module with an enhanced graphical user interface.
 

 
Ruskinn Technology this week announced the launch of its SCI-tive workstation, an in vitro environment designed for both embryonic and adult stem cell isolation, optimization, differentiation, and incubation within an enclosed and controlled environment.
 
Researchers are able to monitor the internal environment of the SCI-tive workstation and control temperature, humidity, and gas concentrations.
 
The workstation has a small lab bench footprint, and reduces the need for other gas-controlled incubators and Class 2 biological safety cabinets, the company said. The Ezee Sleeve Bare-hand System enables all processes to be carried out within the workstation, and integrated microscopy and digital software makes whole process monitoring, tracking, and calibration possible without disturbing the controlled environment.
 
The SCI-tive workstation’s in vitro environment assists compliance with the EU Tissues and Cells Directive (2004/23/EU).
 
The SCI-tive workstation also incorporates Ruskinn’s Gas Mixer Q gas mixing system, enabling cells to be examined under precise O2 and CO2 tension in HEPA-filtered air.
