Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 ?g per million cells in 100 ?l volume. It is recommended that the reagent be titrated for optimal performance for each application.

* APC/Fire? 750 has a maximum excitation of 650 nm and a maximum emission of 787 nm.

The RM4-5 antibody blocks the binding of GK1.5 antibody and H129.19 antibody to CD4⁺ T cells, but not RM4-4 antibody. Additional reported applications (for the relevant formats) include: blocking of ligand binding, in vivo depletion of CD4⁺ cells¹, and immunohistochemistry of acetone-fixed frozen tissue sections^2,3,11 and paraffin-embedded sections¹¹. Clone RM4-5 is not recommended for immunohistochemistry of formalin-fixed paraffin sections. Instead, acetone frozen or zinc-fixed paraffin sections are recommended. The Ultra-LEAF? Purified antibody (Endotoxin < 0.01 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for functional assays (Cat. No. 100575 and 100576).
