Scaling, SADABS – The Champion for Fast Scaling

SADABS is the fast and reliable solution for scaling of crystallographic data.

During data collection with a three-circle or four-circle instrument, the X-ray beam takes different pathways through the crystal producing “true multiplicity” or “multiplicity of observations” (MOO). True multiplicity improves the quality of scaled data and allows a proper error analysis for accurate standard deviations of reflection intensities.

True multiplicity is of key importance for accurately extracting the anomalous signal for SAD phasing. TWINABS — the extension of SADABS — is the world’s best solution for scaling of protein data from twinned crystals.
