SAXNS-RAMBO: BioSAXS Molecular Weight Calculator

If you have buffer-subtracted SAXS data, in standard format (s,I(s),σ), this server will use the method of Rambo & Tainer (2013)
to determine the molecular weight of the object in solution. Check the DNA/RNA box is the major component is composed of nucleotides and not protein.

The possible oligomeric state will also be calculated, based on the monomer's MW

Upload the buffer-subtracted SAXS data "*.dat" file

SAXS Data *.DAT:

Check if S is in nm.

Monomer Molecular Weight (MW) Da

Alternate Molecule Type: DNA/RNA

Rambo Additional Smax: Å-1 In addition to {0.30, 0.40, 0.50, all-data}
