Surplus Lab Store – Smart Science. Smarter Spending
In today’s fast-evolving life sciences landscape, the laboratory is an ever-changing ecosystem—projects pivot, grants expire, or surplus materials accumulate. From C57 mouse models to Sprague Dawley rats, and from fluorescence meters to Qubit fluorometers, many valuable tools risk going unused despite their high quality and demand.
Instruments & Equipment
Qubit Fluorometer
A gold standard for precise nucleic acid and protein quantification, the Qubit fluorometer provides unmatched sensitivity over traditional spectrophotometry. Whether quantifying DNA from C57 mouse liver or validating RNA yield in virus-infected tissues, this compact device remains indispensable
Fluorescence Meter
A core analytical tool, fluorescence meters are used across applications from real-time enzyme kinetics to environmental sensing. Compatible with dyes such as FITC PE and Cyanine 5, it enhances signal detection across multiplexed assays.
MoFlo XDP Cell Sorter
This advanced flow cytometer supports high-speed cell sorting with superior purity and recovery. Ideal for immunophenotyping with fluorochrome PE, Atto647, or Streptavidin Cy5, MoFlo XDP is often deployed in immunology and stem cell studies.
Potassium Quest Assays
These high-throughput screening systems measure intracellular potassium flux, commonly applied in drug discovery, cardiovascular research, and neuronal signaling studies.
AccuCount Beads
Used to calibrate and quantify cells in flow cytometry, AccuCount beads standardize absolute cell counts for viability, apoptosis, and proliferation assays, supporting reproducible data in cancer and immunotherapy research.
Reagents & Fluorescent Dyes
1. Streptavidin Cy5 & Cyanine 5
Fluorescent conjugates like Cy5 and Cyanine 5 are essential in FISH, immunofluorescence, and protein microarray applications. These bright, far-red dyes offer high photostability and minimal spectral overlap.
2. FITC PE & Fluorochrome PE
Popular in multicolor flow cytometry, these tandem dyes facilitate immune cell subset identification in human and murine models. FITC is often combined with Annexin assays for apoptotic cell detection.
3. DiFMUP (6,8-Difluoro-4-methylumbelliferyl phosphate)
A non-fluorescent phosphatase substrate, DiFMUP releases a fluorescent product upon hydrolysis, widely used in phosphatase assays and screening inhibitors in drug development pipelines.
4. Carboxyfluorescein Succinimidyl Ester (CFSE)
CFSE is a membrane-permeable dye that covalently binds intracellular proteins. It is key in cell division tracking and is frequently used in lymphocyte proliferation studies involving C57 or Sprague Dawley models.
5. Atto647
A next-generation fluorophore offering high brightness and stability. Ideal for confocal imaging, FRET experiments, and super-resolution microscopy, especially when used alongside red and near-infrared detection channels.
How to Purchase
Bio Research Supplies LLC buys excess laboratory consumables from companies that are restructuring or going out of business and re-sells them at a substantially discounted price when compared to the retail price you would typically pay when purchasing straight from vendors such as VWR & Fisher Scientific. We only deal in new, unopened, non-perishable lab supplies/consumables and everything goes through our rigorous quality control inspection before it is distributed. In the interim, you can make individual purchases via our eBay store as well as view pictures of each and every item we have for sale.
Our inventory changes quite frequently depending on supply and demand but we always seem to have "core items" such as:
• Pipettes
• Tubes
• Pipette Tips
• Gloves (latex & Nitrile)
• Multiwell Plates
• Cell Culture Supplies (Filters, Petri Dishes, Tissue Culture Flasks)
• Small Equipment (Pipettors, Vortex, Stirplates)
