USED SCIENCE HARDWARE:
- SFP-PCG container
is a lid-covered cylinder containing PCG test-tubes and the cooling capsule - the so-called "ice bag".
 |
| Bundled PCG test-tubes |
PCG experiment uses about 1000 PCG test-tubes, each of which is filled with an individual nonpathogenic chemical substance. PCG test-tube is a sealed Tygon tube, each end of which is sealed by means of double thermal welding. PCG test-tubes are to be bundled, marked according to the test groups and frozen immediately after they are filled.
 |
| The "ice bag" cooling capsule |
The PCG test-tubes are to be placed around the "ice bag" capsule. The capsule is a cylinder containing a material with phase transition (with melting point of minus 30° я).
USED FLIGHT HARDWARE:
- Nikon D3 camera
for taking accompanying pictures.
An experiment session calls for passive exposure of the container with biomaterials onboard ISS RS.

PURPOSE:
- Comparing parameters of protein crystals obtained in zero-gravity with crystals obtained on Earth.
- Obtaining protein crystals that are suitable for X-ray structure analysis.
OBJECTIVE:
Growing protein crystals on ISS RS.
EXPERIMENT RESULTS:
Protein crystals grown in microgravity, as well as accompanying photographic information on a flash memory card.
