Hrp conjugated goat anti rabbit igg

Manufactured by Wuhan Servicebio Technology
Sourced in China

HRP-conjugated goat anti-rabbit IgG is a secondary antibody used in various immunochemical techniques. It is produced by conjugating horseradish peroxidase (HRP) to goat-derived antibodies that specifically recognize and bind to rabbit immunoglobulin G (IgG) molecules. This conjugated antibody can be used to detect and visualize the presence of rabbit primary antibodies in experimental samples.

After fixed in 4% paraformaldehyde for 7 days, lung tissues were embedded in paraffin, cut into slices. After hematoxylin and eosin (H&E) staining, pathological changes were evaluate and scored on a 0–5 severity scale, according to the thickened alveolar walls, cell aggregation, blocked bronchioles and lung consolidation. Infiltration was also evaluated and scored on a 1–4 severity scale.
For immuno-fluorescence assay, the sections were deparaffinized and rehydrated, followed by Citrate-mediated antigen retrieval. After blocking, the primary antibody Anti-Syndecan-1/CD138 Rabbit pAb (cat. no. GB115052, Servicebio), HRP-conjugated goat-anti-rabbit IgG and CY3-Tyramide (cat. no. G1223, Servicebio) were used, followed by Citrate-mediated antigen retrieval. Then another primary antibody Anti-IL-17 Rabbit pAb (cat. no. GB11110-1, Servicebio), secondary antibody HRP-conjugated goat-anti-rabbit IgG and the corresponding iF488-Tyramide (cat. no. G1231, Servicebio) were used. Cell nuclei were stained using 49, 6-diamino-2-phenylindole (DAPI) (cat. no. G1012, Servicebio). The slide scanner Pannoramic MIDI (3DHISTECH) was utilized to image whole slide.

The tissues were made into formalin-fixed paraffin-embedded tissue microarrays and slides, after which we performed dewaxing using xylene and hydration using a grade alcohol series. After citric acid solution or EDTA buffer (pH 9.0) were used for antigen retrieval, 3% H2O2 was applied for the inhibition of endogenous peroxidase. Then the sections were incubated with 5% BSA for 30 min. Next, HRP-conjugated goat anti-rabbit IgG (1:200, Servicebio) was incubated as the secondary antibody for 50 min. Sections were then stained with 3,3-diaminobenzidine (DAB) (Dako). The primary antibodies used were listed as follows: The anti-biglycan primary antibody (diluted 1:2000, Abcam), anti-CD163 primary antibody (diluted 1:500, Servicebio), anti-FOXP3 primary antibody (diluted 1:500, Abcam). Protein expression was assessed with the value of the mean optical density (MOD) using Image-Pro Plus 6.0 software. The definition of BGN positivity was that the ratio of the value of MOD in the tumor tissue to that in the tumor-adjacent tissue of the same patient was greater than 1. Conversely, if the ratio was less than or equal to 1, it was considered BGN negative.

On day 24, mice from each group were euthanized. The lungs and livers were harvested, and the tumor metastatic lesions in the lung were counted. Then, the lung tissues were processed and stained with H&E. Moreover, the distribution of oncolytic adenoviruses in the lung was analyzed by immunohistochemistry using a mouse anti-adenovirus antibody (Abcam, Cambridge, MA) and a goat anti-human decorin antibody (R&D Systems, Minneapolis, MN). Furthermore, the infiltration of lymphocytes, including CD3+ T lymphocytes and macrophages, was also detected by immunohistochemistry using rabbit anti-mouse CD3 (Abcam, Cambridge, MA) and rabbit anti-mouse CD68 (Servicebio, Wuhan, China), respectively. Horseradish peroxidase (HRP)-conjugated rabbit anti-goat immunoglobulin G (IgG) (Servicebio, Wuhan, China) or HRP-conjugated goat anti-rabbit IgG was used as the secondary antibody (Servicebio, Wuhan, China).

Rat kidneys were dissected and fixed in 4% paraformaldehyde and embedded in paraffin, and 4 μm serial sections were then prepared for histological analysis under a light microscope or fluorescence microscope. TdT-mediated dUTP nick-end labeling (TUNEL) was done with an apoptosis detection kit (Servicebio) following the manufacturer’s instructions. Hematoxylin and eosin (HE) staining and periodic acid-Schiff (PAS)[27 (link)] staining were carried out using standard protocols. A random sample of three glomeruli from each rat was analyzed using image analysis software (Image-Pro plus 6.0) to determine the percentage of PAS-positive areas, expressed as a mesangial index. Immunohistochemical (IHC) analyses were carried out using the rabbit anti-AGEs (1:300; bs-1158R; Bioss, Woburn, MA, United States) primary antibodies. HRP-conjugated goat anti-rabbit IgG (1:500; GB23303; Servicebio) was used to detect primary antibodies. The nuclei were subsequently stained with 3,3’-diaminobenzidine, and three fields of view from each rat were digitized. The integrated optical density from all fields was calculated using Image-Pro Plus 6.0.

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.
