Steroid ELISAs

Steroid ELISAs

Cayman Chemical's highly sensitive steroid ELISA kits give reliable and reproducible data. Defining sensitivity as the 80 percent B/B0 value, these steroid ELISAs are compatible with several biological matrices and have broad species reactivity. 

Benefits of using these steroid ELISAs
• Highly sensitive detection in the low pg/ml range
• Compatible with cell culture medium, plasma and serum
• Broad species reactivity
• Wide range of targets
• Strip and solid well formats available
• Designed with competitive assay principals
• Rigorously quality tested

Competitive ELISA standard curve quantitation
Cayman Chemical provides researchers with both the 80 percent B/B0 value and the LLOD along with the assay’s high-low range and 50 percent B/B0 mid-point (the direct centre of the most reliable portion of the curve) to further qualify the ELISA’s robustness.

80 percent binding is the minimum level where reliable, reproducible data can be obtained and represents the minimal functional sensitivity outside of the range of statistical bias.

Competitors typically define by the Lower Limit of Detection (LLOD), usually considered the mean zero plus two standard deviations. While this is the lowest level of analyte detected by the kit, this range is typically not reliable nor reproducible and may reside at a concentration below the linear range of assay. This value typically lies below an assay’s functional sensitivity range.
