Catalog Number:TKPA107Product Name:Alpaca VHHAlias:Alpaca single domain antibody, Variable domain of heavy chain of heavy-chain antibody, sdAbSize:0.1mg,0.5mg,1mgApplications:WB, ELISAIsotype:VHH, sdAbPurity:>90%Buffer:Supplied in PBS, PH7.4Background:Camelids produce two types of antibodies: (i) conventional antibodies made of dimers of heavy and light chains and (ii) a class of IgG devoid of light chain and made of dimers of heavy chains only (HC-IgGs). The HC-IgGs comprise two antigen-binding domains (referred to as VHH or nanobodies). VHHs are the smallest available intact antigen-binding fragments with a molecular weight of around 15 KD. Alpaca VHH (TKPA107) is an isotype control antibody, which can be used as negative controls to help differentiate non-specific background signal from specific antibody signal.Storage:This antibody can be stored at 2°C-8°C for one month without detectable loss of activity.
