Abstract: | ![]() The protein crystallography beamline (PX‐BL21), installed at the 1.5 T bending‐magnet port at the Indian synchrotron (Indus‐2), is now available to users. The beamline can be used for X‐ray diffraction measurements on a single crystal of macromolecules such as proteins, nucleic acids and their complexes. PX‐BL21 has a working energy range of 5–20 keV for accessing the absorption edges of heavy elements commonly used for phasing. A double‐crystal monochromator [Si(111) and Si(220)] and a pair of rhodium‐coated X‐ray mirrors are used for beam monochromatization and manipulation, respectively. This beamline is equipped with a single‐axis goniometer, Rayonix MX225 CCD detector, fluorescence detector, cryogenic sample cooler and automated sample changer. Additional user facilities include a workstation for on‐site data processing and a biochemistry laboratory for sample preparation. In this article the beamline, other facilities and some recent scientific results are briefly described. |
