Protein Interactions 
The study of protein interactions is vital to understanding of how proteins function within cells. Listed here are products to identify and characterize protein interactions by Co-IP, pull-down, far-Western blotting, crosslinking and label transfer.

Chromatin Immunoprecipitation (ChIP Assays) 
Information about chromatin IP (chromatin immunoprecipitation), including the assay steps and recommended reagents for the procedure. 


Co-Immunoprecipitation and Pull-Down Kits 
Convenient kits to affinity purify protein interaction binding complexes via co-immunoprecipitation (co-IP) or non-antibody affinity system (Pull-Down). 


Far-Western Blotting Kits 
Evaluate protein interactions by probing in-gel or on-membrane with biotin-labeled or tagged binding proteins which can be detected secondarily with an HRP-conjugate and sensitive substrate system. 


FeBABE Protein Interaction Mapping Kit 
The Protein Interaction Mapping Kit contains the FeBABE protein cutting reagent, very useful in mapping interaction sites of known proteins. 


In vivo Crosslinking 
Reference guide to in vivo crosslinking and compatible in vivo crosslinkers for investigating cell surface or intracellular protein interactions. 


Label Transfer Reagents 
Biotin-labeled or iodinatable heterobifunctional, cleavable crosslinkers that can be used to tag a bait protein and then transfer the tag onto an interacting protein following a binding interaction. 


Photoreactive Amino Acids 
Photo-Leucine and Photo-Methionine are amino acid analogs that can be incorporated into proteins in actively growing cells. In vivo protein interactions are covalently crosslinked upon UV-light activation of the diazirine moiety. 


UV Lamps for Crosslinker Photoactivation 
Compact, 8-Watt ultraviolet lamp for activating aryl azide and diazirine groups in certain photo-reactive reagents to initiate crosslinking between interacting proteins. Long, midrange, and short wavelength settings allow use with a many techniques. 


Protein Delivery and Expression Assays 
Protein transfection reagent, Small GTPase pull-down kits (Rho, Ras, Rac1, Cdc42, Rap1) and plate-based transcription factor assay kits (NFkB and c-Fos).
