重组Anti-Luteinizing Hormone beta抗体[EPR8195] (ab174265)

This data was developed using ab221494, the same antibody clone in a different buffer formulation.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human pituitary gland labelling ACTH with ab233954 at 1/5000 dilution (0.214 μg/ml) (B), Luteinizing Hormone beta with ab221494 at 1/4000 dilution (0.258 μg/ml) (C) and Growth Hormone with ab155276 at 1/5000 dilution (0.044 μg/ml) (D). Opal Polymer HRP Ms + Rb was used as a secondary antibody, and DAPI was used for a nuclear counter stain. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Panel A: merged staining of anti-Growth Hormone (gray; Opal™690), anti-ACTH (green; Opal™520) and anti-Luteinizing Hormone beta (red; Opal™570) on human pituitary gland.
Panel B: anti-ACTH stained on corticotrophs.
Panel C: anti-Luteinizing Hormone beta stained on gonadotrophs.
Panel D: anti-Growth Hormone stained on somatotrophs.

The section was incubated in three rounds of staining: in the order of ab155276, ab233954, and ab221494 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

Immunohistochemical analysis of paraffin-embedded Human pancreas tissue labeling Luteinizing Hormone beta with ab174265 at a 1/250 dilution.

Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
