Alexa Fluor® 647 Rat Anti-Mouse CD121a
Alexa Fluor® 647 Rat Anti-Mouse CD121a
Flow cytometric analysis of CD121a expression by mouse EL4.IL-2 cells. Cells from the mouse EL4.IL-2 (T lymphoma, ATCC TIB-181) cell line were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with Alexa Fluor® 647 Rat IgG1, κ Isotype Control (Cat. No. 557731; dashed line histogram) or Alexa Fluor® 647 Rat Anti-Mouse CD121a antibody (Cat. No. 563629; solid line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of viable EL4.IL2 cells. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

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 Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.

35F5

The 35F5 monoclonal antibody specifically binds to the Type I Interleukin-1 Receptor (IL-1 RI) which is also known as CD121a. CD121a is expressed by T-cell, fibroblast, and epithelial cell lines such as EL-4 and 3T3. Expression of the 35F5 epitope on normal mouse thymocytes and splenocytes is undetectable by flow cytometry. CD121a is an 80 kDa type-I transmembrane glycoprotein, a member of the Ig superfamily that mediates the inflammatory responses of leucocytes to IL-1. The 35F5 antibody is capable of blocking the binding of IL-1α, IL-1β, and IL-1 receptor antagonist to the Type I IL-1 Receptor. The 35F5 mAb is highly specific for the Type I IL-1 Receptor and does not react with the Type II IL-1 Receptor (CD121b) which is present on mouse macrophage and B-cell lines and polymorphonuclear leukocytes (PMN) and PMN progenitors.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
