BD Horizon™ RY775 Mouse Anti-Human CD45RO
Clone UCHL1 (RUO)
Multiparameter flow cytometric analysis of CD45RO expression on Human peripheral blood leukocyte populations. Human whole blood was stained with BD Horizon™ BV421 Mouse Anti-Human CD45RA antibody (Cat. No. 562885) and with either BD Horizon™ RY775 Mouse IgG2a, κ Isotype Control (Cat. No. 571414; Left Plots) or BD Horizon™ RY775 Mouse Anti-Human CD45RO antibody (Cat. No. 571394/571395; Right Plots). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Samples were acquired using the BD FACSymphony™ A5 SE Cell Analyzer and compensated using FlowJo™ v10.10 Software. Top Plots: The bivariate pseudocolor density plot showing CD45RO expression (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the side and forward light-scatter characteristics of viable leukocytes. Bottom Plots: The bivariate pseudocolor density plot showing CD45RO expression (or Ig isotype control staining) versus CD45RA was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes.

Preparation And Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Product Notices
- When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.

Antibody Details
UCHL1
The UCHL1 monoclonal antibody specifically binds to the 180 kDa isoform of CD45 (aka, the Leukocyte Common Antigen). CD45RO is a type I transmembrane glycoprotein that has cytoplasmic protein tyrosine phosphatase activity and functions in signal transduction pathways. This CD45 isoform does not include amino acid sequences encoded by the variable CD45 exons A, B, or C. CD45RO is expressed on most thymocytes, activated T cells, memory T cells, granulocytes and monocytes, but only on a proportion of resting T cells. CD45RO and CD45RA antibodies seem to define complementary, predominantly non-overlapping, populations in resting peripheral T cells, demonstrating heterogeneity within the CD8 and CD4 subpopulations. CD45RO binds to CD22.

Format Details
RY775
The BD Horizon RealYellow™ 775 (RY775) Dye is part of the BD® family of yellow-green dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 557-nm and an emission maximum (Em Max) at 775-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RY775 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm Blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY775 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter).
