Electron Microscopy Sciences R 3.5/1 Holey Carbon Films on Grids, Grid: Gold. Mesh: 200., 25/PK
QUANTIFOIL is a perforated support foil with pre-defined hole size, shape and arrangement that has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) when compared with conventional holey film. QUANTIFOIL with circular holes is used in cryo-electron tomographic reconstruction. The roundness of the holes is advantageous with respect to the formation of an ice layer of constant thickness. May be preferred over foils with smaller holes if the carbon film should be outside the frame of the image. This option can be desirable in the case of extended objects, such as filamentous objects. Hole size is 3.5 µm. Space between holes is 1 µm. Center to center is 4.5 µm. Grid: Gold. Mesh: 200 .
Sigma Aldrich Fine Chemicals Biosciences RPMI 1640 medum With L gl500ML
RPMI 1640 Medium was developed at Roswell Park Memorial Institute in 1966 by Moore and his co-workers. A modification of McCoys 5A Medium it was formulated to support lymphoblastoid cells in suspension culture but it has since been shown to support a wide variety of cells that are anchorage dependent.
