The Thermo Scientific™ Pierce™ Dilution-Free™ BSA Protein Standards provide a ready-to-use, accurately pre-diluted set of bovine serum albumin (BSA) solutions, designed for fast and reliable standard curve generation in total protein assays. Each kit contains seven calibrated concentrations of BSA and an eighth blank tube, packaged in a multichannel pipette-compatible 8-tube strip, enabling simultaneous transfer of the complete standard curve directly to a 96-well microplate.
This set is optimized for colorimetric protein quantitation assays, such as the Bradford, BCA, and Lowry assays. By eliminating manual dilution steps, the set minimizes pipetting error and ensures enhanced reproducibility and convenience, particularly in high-throughput assay workflows.
Key Features & Benefits
-
Dilution-Free, Ready-to-Use Format
Eliminates time-consuming and error-prone serial dilutions with 7 pre-diluted BSA concentrations. -
Multichannel Pipette-Compatible
The tubestrip format allows fast and consistent transfer into microplates for standard curve generation. -
High Accuracy & Traceability
Standards are prepared from NIST-calibrated BSA stock solutions for dependable quantitation. -
Assay Versatility
Ideal for BCA, Bradford, Lowry, and UV absorbance (A280)-based protein assays. -
Convenient Blank Inclusion
An eighth tube in the strip is left empty for adding assay buffer, allowing accurate blank subtraction. -
Stable & Ready for Use
Supplied in 0.9% saline with 0.05% sodium azide for long-term stability at 2–8°C.
