Quantigold is for quantitative determination of low protein concentration. It is a fast, sensitive assay which is ideal for accurately detecting nanogram quantities of protein in solution. By capitalizing on the affinity of protein to colloidal gold, this assay creates a stable color formation which may be read by a spectrophotometer set at 595 nm. Protein quantities can be interpolated from the BSA standard curve, which is linear in the 5-200 ng range.
- Sensitive: 100 times more sensitive than other dye-binding assays.
- Quick and Easy: One-step, one-solution assay that can be completed in 40-60 minutes.
- Stable: Accurate results, readable up to 24 hours following completion of the assay.
Quantigold provides a convenient assay system that requires only minimal amounts of valuable protein samples. The only materials required are: Quantigold, Type 1 or distilled/deionized water, micropipettes, 1.5 ml clear microfuge tubes, and disposable micro-assay cuvettes (1.0 ml).
Storage and stability: Quantigold is stable for at least 6 months at 4°C. Do not freeze.
