Representative standard curve using ab13639.
![Parallelism experiments were carried out to determine if the recombinant standard accurately determines [pSer326] HSF1 concentrations in biological matrices. Values were obtained using cell lysates from treated and untreated cells serially diluted in the assay buffer and assessed from a standard curve using four parameter logistic curve fitting.The observed values were plotted against the dilution factors.

HeLa and 3T3 cells were grown to approximately 80% confluency and subjected to heat shock at 42ºC for 2 hours. Extracts were prepared as described in “Sample Preparation” and the levels of HSF1 were determined in the assay. Induction is expressed as the fold change relative to non heat-shocked control samples.
