FAQ

How is the recombinant Protein L produced?

The soluble Protein L products in the collection are described as recombinant proteins expressed in E. coli. Tag and labeling format vary by product.

Which soluble Protein L formats are available?

The list includes His-tagged, biotinylated His/Avi and PE-labeled Protein L formats. Choose the format according to the capture or detection method.

How do I know whether Protein L will bind my antibody?

Check the antibody light-chain class and subtype first. Protein L should not be assumed to bind lambda light chains or every kappa subtype.

Can Protein L detect Fab, scFv or domain-antibody formats?

Yes. Because Fc is not required, Protein L can bind compatible Fab, scFv and domain-antibody formats when they contain a recognized kappa light chain.

What does recombinant Protein L bind on an antibody?

Protein L binds compatible immunoglobulin light chains rather than the Fc region. Its binding is restricted to certain kappa light-chain subtypes.

    PE-Labeled Recombinant Protein L, His Tag (Site-specific conjugation)
    The pl antibody can detect the scfv region of most antigen CARs. We use it to detect the scfv of CD33 in our CD33 CAR-NK, and it can also be diluted with good results!

    Recombinant Protein L, His Tag, low endotoxin
    I used recombinant protein L from ACROS Biosystems to prepare gold conjugates for immunosensors and rapid quantification of human IgG and was able to detect 2.5 ng of Human IgG in less than 1 minute. I highly recommend this product for the detection and isolation of antibodies and Fab'2 fragments. I will definitely be ordering this item again.
