Asymmetric Curves

Many dilution curves are too asymmetric to be fit accurately with the symmetrical 4PL. These bad fits at the upper and lower ends of the curves affect parallelism and potency results. STATLIA MATRIX’s 5PL is the best in the industry and will easily fit your assay’s curves whatever their shapes. The manuscript on the software’s 5PL model has been cited more than 300 times. STATLIA MATRIX is the industry software with the best weighting to meet the FDA guidelines for “appropriate weighting.”
