W19210A_ULEAF_CD44_Antibody_1_122022
Murine B-cells were isolated using the MojoSort™ Mouse Pan B Cell Isolation Kit (Cat. No. 480051) and activated overnight with 20 ng/mL recombinant mouse IL-4 (carrier-free) (Cat. No. 574302) and 10 µg/mL purified anti-mouse IgM (Cat. No. 406501). Activated B cells were seeded onto tissue culture plates pre-coated with 20 µg/mL Ultra-LEAF™ purified anti-mouse CD44 (clone W19210A) or isotype control. After 4 hours, the number of elongated cells (circularity < 0.5) was quantified using brightfield imaging and morphometric analysis with ImageJ. The assay was performed in triplicate, and 4 images per well at 20x magnification were analyzed. Data shown are normalized to rat IgG2a, κ isotype control treated wells.

After 4 hours, cells were fixed with Fixation Buffer (Cat. No. 420801) and stained with Flash Phalloidin™ Green 488 (Cat. No. 424201) in Intracellular Staining Permeabilization Wash Buffer (10X) (Cat. No. 421002). Images were taken using a 40x objective.

Description

CD44 is an 80-95 kD glycoprotein also known as Hermes, Pgp1, H-CAM, or HUTCH. It is expressed on all leukocytes, endothelial cells, hepatocytes, and mesenchymal cells. As B and T cells become activated or progress to the memory stage, CD44 expression increases from low or mid levels to high levels. Thus, CD44 has been reported to be a valuable marker for memory cell subsets. High CD44 expression on Treg cells has been associated with potent suppressive function via high production of IL-10. CD44 is an adhesion molecule involved in leukocyte attachment to and rolling on endothelial cells, homing to peripheral lymphoid organs and to the sites of inflammation, and leukocyte aggregation.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
