Protein A, Electron Microscopy Sciences

Supplier: Electron Microscopy Sciences
25282 25284 25283 25286 25285 25288 25287 25289
This protein A provides maximum resolution in two-step labeling.

  • Gold particle sizes of 6, 10 ,15 and 25 nm
  • Monodisperse particle population
  • Minimal size variation and overlap
  • Maximum of one gold particle per primary antibody

The monodisperse size population makes the conjugates suited for multiple labeling with no overlap. The Conventional Immunogold Reagents are the classical conjugates in immuno electron microscopy; they are a good choice when the antigen is abundant and the accessibility of the antigen is relatively good. The conventional labeling approach in transmission and scanning electron microscopy utilizes secondary immunogold reagents based on particles that can be observed without enhancement. These conjugates are suited for single and multiple labeling in electron microscopy, when the number of antigens available for binding is such that a relevant signal can be obtained.

Delivery information: The reagents are supplied in PBS with 1% Bovine Serum Albumin and 15 mM NaN3 at an OD 520 nm of 1.0.
