Ihc zinc fixative solution

Manufactured by BD

IHC zinc fixative solution is a laboratory reagent used for the preservation and preparation of biological samples for immunohistochemical (IHC) analysis. It functions as a fixative, stabilizing the cellular structure and proteins within the sample to prevent degradation.

Tissues were cut into 2-3 mm slices and fixed in IHC zinc fixative solution(Beckstead, 1994 (link)) (BD Biosciences) for 24 hours at room temperature (RT). After rinsing with tap water for 45 min, tissues were dehydrated at RT for 45 min each with 70% ethanol, 95% ethanol 100% ethanol and xylene, respectively. Tissues were infiltrated in paraffin at 58°C for 45 min using a Sakura Tissue-Tek®IV Embedding center (Sakura, Mars, PA). Tissue sections were prepared by cutting at 4 μm and floated out on a water bath at 43°C and collected on coated glass slides (SuperFrost/Plus; Fisher Scientific, Pittsburgh, PA). The slides were dried at RT for overnight.

Immunohistochemical Analysis of Adhesion Lesions

Immunohistochemistry was performed to test whether fibrinogen and collagen type I were present in the adhesion lesions and exudates. Tissue specimens were fixed for 24 h in IHC Zinc fixative solution (BD Biosciences) and embedded in paraffin wax before sectioning. Sections of 4 µm thickness for each specimen were prepared on peeling prevention coated slide glass (Matsunami Glass Ind.) and stained with hematoxylin and eosin (H&E). For immunohistochemistry, the sections were preincubated with serum-free protein block (Agilent Technologies) for 30 min at room temperature and primary antibodies for fibrinogen (ab92572, Abcam) and collagen type I (F56, Kyowa Pharma Chemical Co. Ltd.) diluted in PBS were added to each slide overnight at 4 °C. Secondary antibody staining was performed using the Histofine Simple Stain MAX-PO (Nichirei) according to the manufacturer’s instructions. The staining was visualized under a Nikon Eclipse TS-100 microscope (Nikon, Tokyo, Japan).

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.
