I have recently discovered this site. I have a question regarding reagents. We have been testing the Caltag monoclonal kappa/lambda/cd19 antbody cocktail and comparing it to the same BD combination to try and get a brighter CD19 signal for use in a clinical flow lab. I have noticed a couple of cases in which the BD reagent shows no evidence of a light chain restriction but the Caltag reagent does (usually a very low percentage, dim kappa). Has anyone else seen this? The population could not be confirmed with polyclonal kappa and lambda from BD or Tago.
