86-7909-77 ［取扱停止］Biotinylated Recombinant Protein L Protein, His Tag, ultra sensitivity (primary amine labeling, long spacer) 500ug RPL-P814R
特徴
- Background：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, from which the name was suggested.
- 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).
- In humans and mice, kappa (k) light chains predominate.
- The remaining immunoglobulins have lambda (l) light chains.
- The recombinant protein contains four immunoglobulin (Ig) binding domains (Bdomains) of the native protein.
- 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 (Dabs).
