Expansion Microscopy (ExM) promises an easier, more accessible way to image biological features previously only visible via techniques like super-resolution microscopy or electron microscopy. Since its introduction in 2015 by the Boyden Lab, ExM has been steadily growing in ...
Addgene is excited to announce the launch of our partnership with the Institute for Protein Innovation (IPI). Together, we’ll be working to provide researchers with a collection of IPI’s well-validated and ready-to-use recombinant antibodies. The first collection, a set of ...
IBEX is a highly multiplexed tissue imaging method that uses iterative staining and chemical bleaching to allow for high-resolution imaging without degrading the tissue (Radtke et al., 2020, 2022). I do mean highly multiplexed: you can image over 65 different parameters using ...
You may be familiar with immunofluorescence (IF, often referred to as immunocytochemistry (ICC) when the sample is cultured cells or immunohistochemistry (IHC) with tissues), where an antibody binds a target protein in your sample, then a fluorescently labeled secondary antibody ...
When it comes to using antibodies in the lab, we focus on a lot on the variable domain and not so much on the constant, or Fc, domain. Sure, we all know that the Fc domain provides structure, determines isotypes, and provides a place for secondary antibodies to bind. We also ...
The stress of finding a ‘good’ antibody is something we’ve all experienced. Finding an antibody that works for your application, specifically detects your protein, is species compatible, and doesn’t come with a high background can be a huge challenge. Epitope tags eliminate the ...
You are a scientist looking to determine how Protein A and Protein B interact. You read extensive research on the two proteins and come up with a great experimental plan that requires indirect staining of both targets in your specimen. You scour the literature and find an ideal ...
If you are lucky in lab life, you will have a plethora of antibody options for your experiment (all well validated for your application, of course!) When the stars are aligned and the lab gods are smiling down at you, you may wonder which antibody should I pick? Do I go for the ...
