Immunohistochemical Analysis of p53 Expression

Immunohistochemistry was performed on 4 μm sections that were
cut from FFPE (formalin-fixed, paraffin-embedded) blocks. Sections were then
deparaffinised with xylene and rehydrated through graded ethanol. Antigen
retrieval was achieved with a pH 9.5 Nuclear Decloaker (Biocare Medical) in a
Decloaking pressure cooker at 95°C for 40 min. Tissue sections were then
treated with 3% hydrogen peroxide (LOT 161509; Fisher Chemical) and with
Background Sniper (Biocare Medical, Concord, CA, USA) to reduce nonspecific
background staining. Primary antibody for p53 (Cell Signaling, 2527) was applied
in a 1:150 dilution for 80 min followed by detection with the MACH 3 Rabbit HRP-
Polymer Detection kit (Biocare Medical). Visualization was achieved using VECTOR
NovaRED (SK-4800; Vector Laboratories, Inc.) as chromogen. Lastly, sections were
counterstained with Tacha's Automated Hematoxylin (Biocare Medical).

Immunohistochemical Analysis of Blood Group Antigens

Samples from human parathyroid glands (n = 3), and thyroid glands (n = 3) were fixed in buffered 4% paraformaldehyde, dehydrated, and embedded in paraffin. Subsequently, 4 µm sections were mounted on Superfrost Plus glass slides (Menzel) and microwave treated for antigen retrieval. Immunostaining was performed after pretreatment with Diva Decloaker 20X (Biocare Medical, Pacheco, CA, USA) at 95 °C for 40 min and blocking reagent Peroxidazed 1 (Biocare Medical). The primary antibodies used were anti-blood group A antigen (clone HE-193, dilution 1:50, cat. No. ab2521, Abcam, Cambridge, England), anti-blood group B antigen (HEB-29, 1:50, ab2524, Abcam), anti-H-type-1 (17–206, 1:50, ab3355, Abcam), and anti-GD1a ganglioside (GD1a-1, 1:50, MAB5606Z, Sigma-Aldrich, St. Louis, MO, USA). MACH 1 Universal HRP-polymer kit (Biocare Medical), including Betazoid DAB substrate and blocking reagent Background Sniper, was used for detection of bound antibodies. Nuclei were counterstained with Tacha’s automated hematoxylin (Biocare Medical).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
