Confocal immunofluorescent analysis of THP-1 cells (left, positive) and Jurkat cells (right, negative), using CD68 (D4B9C) XP® Rabbit mAb (Alexa Fluor® 555 Conjugate) (red). Samples were mounted in ProLong® Gold Antifade Reagent with DAPI #8961 (blue).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 555 fluorescent dye and tested in-house for direct immunofluorescent analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated CD68 (D4B9C) XP® Rabbit mAb #76437.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
NOTE: Cells should be grown, treated, fixed and stained directly in multiwell plates, chamber slides or on coverslips.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

CD68 (D4B9C) XP® Rabbit mAb (Alexa Fluor® 555 Conjugate) recognizes endogenous levels of total CD68 protein.
Monoclonal antibody is produced by immunizing animals with recombinant human CD68 protein.
CD68 (macrosialin) is a heavily glycosylated transmembrane protein that is expressed by and commonly used as a marker for monocytes and macrophages (1, 2). It is found on the plasma membrane, as well as endosomal and lysosomal membranes (1-3). It is proposed to bind OxLDL and has been observed as a homodimer (3, 4).
