Description

Mouse Monoclonal Antibody

This 9M1-3 monoclonal antibody reacts with human Galectin-9. Galectin-9 is one of fifteen members of the galectin family of glycan-binding proteins. It is expressed on activated T helper cells and Foxp3+ T regulatory cells and plays a critical role in the regulation of immune function. Interaction of Galectin-9 with its ligand, TIM3, induces apoptosis in Th1 and Th17, inhibits Th17 polarization and IFN gamma expression, and drives Treg expansion. Galectin-9 is also thought to contribute to the survival and expansion of some tumors by inhibiting the anti-tumor response and promoting immune evasion. Along with Galectin-1 and Galectin-3, high levels of Galectin-9 expression are associated with poor cancer prognosis, making these potential therapeutic targets. Applications Reported: This 9M1-3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 9M1-3 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 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. eFluor 660 is a replacement for Alexa Fluor 647. eFluor 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitati...

The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. The protein encoded by this gene is an S-type lectin. It is overexpressed in Hodgkin's disease tissue and might participate in the interaction between the H and RS cells with their surrounding cells and might thus play a role in the pathogenesis of this disease and/or its associated immunodeficiency. Multiple alternatively spliced transcript variants have been found for this gene.

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.

Is the eFluor 660 fluorochrome compatible with Anti-Cy5/Alexa Fluor 647 beads?

Yes, in-house studies have demonstrated that the eFluor 660 fluorochrome is recognized by Anti-Cy5/Alexa Fluor 647 beads. Side by side studies with Alexa Fluor 647 versus eFluor 660 conjugated antibodies have demonstrated comparable results.

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.
