クローン 4H9 (also known as Leu-9; Leu9)

(RUO)

Multiparameter flow cytometric analysis of CD7 expression on Human peripheral blood leucocytes. Human whole blood was stained with BD Horizon™ R718 Mouse Anti-Human CD3 antibody (Cat. No. 566953) and with either BD Horizon™ BV421 Mouse IgG2a, κ Isotype Control (Cat. No. 562439; Left Plots) or BD Horizon™ BV421 Mouse Anti-Human CD7 antibody (Cat. No. 568323/568324; Right Plots). Erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plots showing the correlated expression of either CD7 (or Ig Isotype control staining) versus CD3 (Top Plots) or side light-scatter (SSC-A) signals (Bottom Plots) were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes (Top Plots) or leucocyte populations (Bottom Plots). Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Preparation and Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.

推奨アッセイ手順

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.

For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant™ Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant™ Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant™ Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant™ Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant™ Stain Buffer Plus (Cat. No. 566385).

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.
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.

4H9

The 4H9 (Leu-9) monoclonal antibody specifically recognizes human CD7 which is also known as T-cell leukemia antigen, T-cell surface antigen Leu-9, and LEU-9. CD7 is a ~40 kDa type I transmembrane glycoprotein that has an extracellular region with an N-terminal IgV-like domain followed by an extended O-glycosylated stalk region, a transmembrane region and cytoplasmic tail. The CD7 antigen is expressed throughout T-lymphocyte differentiation. It is present on 85% to 90% of peripheral blood T lymphocytes. In normal individuals, CD7 is expressed on all CD8+ lymphocytes, approximately 90% of CD4+ lymphocytes, and most NK cells. CD7 is weakly expressed on monocytes but not on granulocytes or B lymphocytes. It is expressed on hematopoietic progenitors and 50% of thymocytes. In leukemias, the CD7 antigen is present on the majority of T-lymphoid lineages. CD7 may function in cellular adhesion and play a role in interactions between T cells as well as T cells and B cells.

BV421

The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
