Description

CD45RA is a 205-220 kD single chain type I glycoprotein. It is an exon 4 splice variant of the tyrosine phosphatase CD45. The CD45RA isoform is expressed on resting/naïve T cells, medullary thymocytes, B cells and monocytes. CD45RA enhances both T cell receptor and B cell receptor signaling. CD45 non-covalently associates with lymphocyte phosphatase-associated phosphoprotein (LPAP) on T and B lymphocytes. CD45 has been reported to be associated with several other cell surface antigens including CD1, CD2, CD3, and CD4. CD45 has also been reported to bind galectin-1. CD45 isoform expression can change in response to cytokines.

Product Details

Verified Reactivity: Human
Reported Reactivity: Chimpanzee
Antibody Type: Monoclonal
Host Species: Mouse
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation: The antibody was purified by affinity chromatography and conjugated with Spark Blue™ 574 under optimal conditions.
Concentration: 0.2 mg/mL
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: FC
Recommended Usage: Flexi-Fluors™ are provided at a standard 0.2 mg/mL concentration. We recommend titrating this reagent to determine the optimal concentration for each application. For many flow cytometry applications, conjugated antibodies perform well at concentrations ranging from 0.03 to 1.0 µg per million cells in 100 µL. We recommend testing a range of concentrations starting from 10 µg/mL.

For example, make five 1:1 serial dilutions of the 0.2 mg/mL antibody. Add 5 µL of each dilution (including the undiluted antibody) to 100 µL of cells (at 10⁷ cells/mL) to test six concentrations -- 1.0, 0.5, 0.25, 0.125, 0.06, and 0.03 µg per million cells in 100 µL volume. Compare staining patterns or create a titration curve using the MFI or staining index to determine the optimal concentration.
Excitation Laser: Blue Laser (488 nm)
Application Notes: Additional reported applications (for relevant formats of this clone) include: inhibition of CD45 functions², immunohistochemical staining of frozen tissue sections³ and formalin-fixed paraffin-embedded tissue sections⁴, and immunocytochemistry^15,16.

Related FAQs

What are Flexi-Fluors?

Flexi-Fluors are rapidly made-to-order conjugated antibodies. The technology, manufacturing processes, and specifications used to create Flexi-Fluors are the same as our regular catalog products. However, the optimal concentration and performance of each Flexi-Fluor must be determined by the customer.

How quickly will I receive my order?

We aim to ship Flexi-Fluors within 2-3 weeks of receipt of your order. However, depending on your location, shipping times may vary.

How are Flexi-Fluors different from regular catalog products?

Flexi-Fluors are made on demand, specifically for you. Flexi-Fluors are manufactured using the same high-quality standards, and specifications as other catalog products. For faster delivery, Flexi-Fluors are not tested by flow cytometry to determine optimal concentrations or evaluate performance. This testing needs to be performed by the customer.

How do I determine the optimal concentration for using my Flexi-Fluor? How should I titrate my antibody?

Flexi-Fluors are provided at a standard 0.2 mg/mL concentration. We recommend that you titrate your antibody to determine the optimal concentration to use for your application. For many flow cytometry applications, conjugated antibodies perform well at concentrations ranging from 0.03 to 1.0 µg per million cells in 100 µL volume. We recommend that you test a range of concentrations starting from 10 µg/mL.

For example, make five 1:1 serial dilutions of your 0.2 mg/mL antibody. Add 5 µL of each dilution (including the undiluted antibody) to 100 µL of cells (at 10⁷ cells/ml) to test six concentrations - 1.0, 0.5, 0.25, 0.125, 0.06, and 0.03 µg per million cells in 100 µL volume. Compare staining patterns or create a titration curve using the MFI or staining index to determine the optimal concentration.

I can’t find the antibody-dye combination that I need. When will it be available?

We continuously update our catalog, introducing scores of new products every month. Please get in touch with our Technical Service team for an update on new products or recommendations for suitable alternatives to complete your panel. Or contact Custom Solutions to inquire about our affordable custom conjugation services.

I need help to validate the performance of my Flexi-Fluor. Who should I contact?

Please get in touch with Technical Service for assistance.

Can I order more than 50 μg of a Flexi-Fluor?

Yes, you can order multiple vials of the same Flexi-Fluor products. We cannot guarantee, however, that these vials will be bottled from the same lot. For bulk single-lot orders, contact our Custom Solutions team.

What is the expiration date of my Flexi-Fluor?

Expiration dates can be found on the vial label or by using our CoA lookup tool.
