FITC荧光大鼠IgG2c，kappa [RTK4174] -同型对照(ab114134)

Thank you for attending our webinar on Immunoprecipitation last week. We hope you enjoyed it and it was useful for you. We would also like to thank you for sending your question and apologize that we were not able to answer it in the Q&A session. Isotype controls are used to confirm that the primary antibody binding is specific and not a results of non-specific Fc receptor binding or other protein interactions. The isotype control antibody should match the primary antibody’s host species, isotype, and conjugation. For example, if the primary antibody is a FITC-conjugated rat IgG1, then you will need to choose a FITC-conjugated rat IgG1 isotype control such as ab114134. Most isotype controls are monoclonal. They are not suitable for use with polyclonal antibodies as these contain more than one IgG subclass. However, we do provide several polyclonal isotype controls for use in these circumstances. To find a suitable isotype control on our website, go to the 'Products' section of the top navigation menu. Choose "Isotype control", then the species and subclass of your primary antibody. This will give you a range of isotype controls for use with that species and isotype of primary antibody. The use of a particular isotype control is illustrated in the cited references which can be found on most datasheets.  I hope this information is helpful to you. Our Scientific Support team is always at your service, should you require further expert advice. I am happy to let you know that we now also provide our Scientific Support in Spanish!
