SAXNS-RAMBO: BioSAXS Molecular Weight Calculator

If you have buffer-subtracted SAXS data, in standard format (q,I,σ), this server will use the method of Rambo & Tainer (2013)
to determine the molecular weight of the object in solution. The possible oligomeric state will also be calculated, based on the monomer's MW

The Output is scaled so that Io = MW (Da) {--The Output may include a zero offset if the curve extends beyond I/σ≤2. --}
