Description

Mouse Monoclonal Antibody

This 4H3 monoclonal antibody recognizes human CD137 ligand, also known as 4-1BB ligand, TNFSF9, or CDw137L. Applications Reported: This 4H3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 4H3 antibody has been pre-diluted and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This may be used at 5 μL (0.06 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor™ 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 μL of cell sample + 100 μL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirica...

CD137 ligand (CD137L) is a type II membrane protein and part of the TNF superfamily. CD137L is a co-stimulatory molecule that is expressed on antigen presenting cells (DCs, monocytes/macrophages, B cells) and is upregulated upon activation. Its receptor, CD137/4-1BB, is found on a variety of cells, including inflamed endothelial cells, where its expression enhances extravasation of CD137L expressing monocytes. Activated T cells also express CD137, and engagement with CD137L enhances T cell proliferation, IL-2 secretion, survival, and cytotoxic activity. CD137L is also expressed on a majority of B-cell lymphomas, including mantle cell lymphoma, follicular lymphoma, and diffuse large B-cell lymphoma (but it is lacking on Hodgkin lymphoma and T-cell lymphoma). CD137L is also expressed in carcinoma cell lines, and is thought to be involved in T cell-tumor cell interactions.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
