Open Dataset XSQIWPPC



NSP12 is the RNA dependent RNA polymerase (RdRp) from SARS CoV2.

Experimental description

The full SEC-SAXS trace set is available here. Each fame is a 2 second exposure and since collected on a direct detector there is nearly no time separation between frames. The buffer was 20mM Hepes, 150 mM NaCl, 1 mM TCEP pH 7.5. Non Structural Proteins 12 is the RNA dependent RNA polymerase (RdRp) from SARS CoV2. This protein was expressed in E. Coli and purified, sent to SIBYLS for collection and then purified again as part of the SEC-SAXS process. The full SEC-SAXS elution set is here for further analysis.

File description

Each file name is numerically iterated so that *_00009.cbf.dat is the 9th SAXS frame from the elution trace. Since it is the 9th frame it is collected 18 seconds after the instrument began recording. The merged NSP12.dat file for an SEC peak region is included.
