Pre-Made Buffers Save Time and Reduce Error
Skip the weighing, dissolving, and pH adjustment. Our pre-made biology buffers are manufactured with reagent-grade chemicals, filtered through 0.2 µm membranes, and QC-tested for pH accuracy and sterility. Available as ready-to-use 1× solutions or concentrated stocks (5×, 10×, 20×, 50×) for labs that prefer to dilute on-site.
TAE vs. TBE for gel electrophoresis
| Property | TAE (Tris-Acetate-EDTA) | TBE (Tris-Borate-EDTA) |
|---|---|---|
| Resolution | Good for large DNA (>2 kb) | Better for small DNA (<1 kb) |
| Buffer Capacity | Lower — exhausts faster | Higher — lasts longer |
| Run Time | Standard | Longer (higher ionic strength) |
| DNA Recovery | Better — acetate does not inhibit ligase | Borate can inhibit enzymatic reactions |
| Best For | Gel extraction, cloning, routine sizing | Small-fragment resolution, sequencing gels |
We carry multiple PBS formulations: PBS (pH 7.4) for general washing, DPBS (Dulbecco’s) with and without calcium/magnesium for cell culture, and PBST (PBS + 0.05% Tween-20) ready-to-use for western blot and ELISA washing. Choose the right formulation for your application—calcium-free DPBS is required for trypsinization protocols.
Biology Buffer FAQ
Most pre-made buffers have a 2–3 year shelf life when stored at room temperature in sealed containers. Sterile-filtered buffers (like PBS for cell culture) should be stored according to label instructions, typically at 2–8°C after opening.
Buy 1× if you want convenience and no dilution error. Buy concentrated stock (10×, 50×) if you use large volumes and want to save on shipping costs and storage space. A 1 L bottle of 50× TAE makes 50 L of working buffer.
Buffers intended for cell culture (PBS, DPBS) are sterile-filtered through 0.2 µm membranes and packaged aseptically. Electrophoresis buffers (TAE, TBE) are not sterile but are filtered to remove particulates.
Yes. We offer TE buffer without EDTA (Tris-only) and PBS without EDTA for applications where chelation interferes with downstream reactions, such as certain enzyme assays and metal-dependent protocols.
