Description:RecombinantmonoclonalantibodytoHIV-1/HIV-2protease.ManufacturedusingAbAb’sRecombinantPlatformwithvariableregions(i.e.specificity)fromthehybridoma1696.ThisisaFabfragmentwithahis-tag.
SpeciesandIsotype:MouseFabfragment,His-Tagged,kappa
CloneNumber:1696
UniProtAccessionNumberofTargetProtein:
PublishedApplication(s):Neutralize;ELISA;WB
PublishedSpeciesReactivity:HIV-1;HIV-2
Immunogen:1696waspreparedbygeneratingahybridomacellline,fusingmyelomacellswithsplenocytesderivedfromBALB/cmiceimmunizedwithHIV-1PRinthepresenceofFreund"sadjuvant.
