Sizing of protein A-colloidal gold probes for immunoelectron microscopy
Gold particles in colloidal solutions often vary considerably in size. The finest sols (diameter less than 15 nm), especially, are very heterogeneous, as is indicated by coefficients of variance (CV) of 25-35%. We have complexed staphylococcal protein A with gold particles (PA/Au) and then fractionated the preparations by glycerol or sucrose gradient centrifugation into very homogeneous subfrac...
متن کاملUse of colloidal gold particles in double-labeling immunoelectron microscopy of ultrathin frozen tissue sections
Complexes of protein-A with 5 and 16 nm colloidal gold particles (PA/Au5 and PA/Au16) are presented as sensitive and clean immunoprobes for ultrathin frozen sections of slightly fixed tissue. The probes are suitable for indirect labeling and offer the opportunity to mark multiple sites. The best procedure for double labeling was to use the smaller probe first, i.e., antibody 1 - PA/Au5 - antibo...
متن کاملDNA probes on chip surfaces studied by scanning force microscopy using specific binding of colloidal gold.
Single-stranded DNA was covalently bound on chip surfaces using two different silanization procedures. The resulting surfaces were characterized by fluorescence and scanning force microscopy using sequence-complementary DNA molecules with labels. Colloidal gold (30 nm) was used as the topographic label. Scanning force microscopy revealed the individual labels on the surface and their distributi...
متن کاملNew silver-gold intensification method of diaminobenzidine for double-labeling immunoelectron microscopy.
The available methods for double-labeling preembedding immunoelectron microscopy are highly limited because not only should the ultrastructure be preserved, but also the different antigens should be visualized by reaction end products that can be clearly distinguished in gray-scale images. In these procedures, one antigen is detected with 3,3'-diaminobenzidine (DAB) chromogen, resulting in a ho...
متن کاملImmunoelectron microscopy of human retroviruses.
The ultrastructural detection and identification of human retroviruses--HTLV (human T-cell lymphotropic virus) and HIV (human immunodeficiency virus)--have become an everyday task for pathologists and virologists as well as for cell and molecular biologists. The development of better and conventionally available immunocytochemical techniques, such as pre- or postembedding immunocytochemical met...
