Protein L, PerCP conjugated
Protein L was isolated from the surface of bacterial species Peptostreptococcus magnus and was found to bind Ig(IgG,IgM,IgA,IgE and IgD) through L chain interaction. The recombinant protein contains four immunoglobulin (Ig) binding domains (Bdomains) of the native protein. Recombinant Protein L Protein, fused with the polyhistidine tag at N-terminus and a single cysteine at C-terminus. DTT-reduced protein migrates as a 36 to 38 kDa polypeptide.
Peridinin, a light-harvesting carotenoid, is associated with chlorophyll, which binds the protein subunits to form the peridinin-chlorophyll-protein light-harvesting complex (PerCP) in dinoflagellates, best studied in Amphidinium carterae..
Protein L, PerCP conjugated is a protein labeled by PerCP.
Formulation: 100 µg of Protein L conjugated with PerCP in PBS.
Excitation Laser: Blue Laser (482 nm)
Application: In 0.1 ml PBS
Immunofluorescence (IF) 1: 50-1:200

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Despite this wide-ranging binding capability with respect to Ig classes, Protein L is not a universal immunoglobilin-binding protein. Binding of Protein L to immunoglobulins is restricted to those containing kappa light chains (i.e., k chain of the VL domain). Besides antibody, protein L is also suitable for binding of a wide range of antibody fragments such as Fabs, single-chain variable fragments (scFv), and domain antibodies.
