Recombinant Staphylococcal L Protein, biotin-labeled

• Cat.No.: Protein L-528
• Product Overview: Recombinant Staphylococcal L Protein was conjugated with biotin.

Specification

• Description: Protein L is a cell surface protein from Peptostreptoccocus magnus that binds to the variable light chains (kappa chain) of immunoglobulins without interfering with antigen binding. In contrast to IgG-binding proteins, such as protein A and protein G, protein L can be used for the detection and purification of mammalian kappa light chain antibodies of all classes. Biotin-Protein L, which is produced by covalently linking biotin to protein L, can be used in immunodetections, such as immunoblotting (western or dot blot), ELISA, and immunohistochemistry.
• Species: Peptostreptoccocus magnus
• Form: 1 mg/ml, lyophilized with PBS, pH 7.4, containing 1% BSA and 0.02% sodium azide.
• Storage: The product is stable in lyophilized form if stored at -20 centigrade or below. The reconstituted product can be stored for 2-3 weeks at 2-8 centigrade. For long term storage, aliquot and store at -20 centigrade or below. Avoid repeated freezing and thawing cycles.
• Reconstitution: Reconstitute the lyophilized product with deionized water (or equivalent) to the final concentration of 1.0 mg/ml.
