Hrp conjugated donkey anti rabbit secondary antibodies

Manufactured by Abcam

HRP-conjugated donkey anti-rabbit secondary antibodies are laboratory reagents used to detect the presence of rabbit primary antibodies in various immunoassays. These antibodies are conjugated with horseradish peroxidase (HRP), an enzyme that catalyzes a colorimetric reaction, enabling the visualization and quantification of target proteins or antigens.

The protein expression levels of CCL13 and KLRC1 were estimated via immunohistochemical (IHC) staining. Briefly, the tissues slides were deparaffinized, rehydrated and treated with 3% H2O2 for 15 min to eliminate endogenous peroxidase. Then, antigen retrieval was performed by heating the slides in sodium citrate buffer for 3 min. Next, the slides were incubated with rabbit anti-CCL13 or anti-KLRC1 primary antibodies (Affinity, Biosciences, 1:200) at 4°C overnight. The slides were washed and incubated with HRP-conjugated donkey anti-rabbit secondary antibodies (Abcam) for 15 min. The staining was visualized using DAB solution and samples were counterstained with hematoxylin.
Immunostaining of CCL13 and KLRC1 were analyzed by two pathologists who were blinded to the same information. The staining intensity score was defined on a scale of 0 to 3 in which 0 means no staining, 1 means mild staining, 2 means medium staining and 3 means intense staining. The percentage score of stained cells were also calculated on a scale of 1 to 4 in which 1 represents (0–25%), 2 = (26–50%), 3 = (51–75%) and 4 = (76–100%). In order to obtain the final score, the intensity score and percentage score were multiplied to reach the final score ranging from 0 to 12.

Western Blot Analysis of Liver Cancer Cell Proteins

Treated liver cancer cells were lysed in RIPA buffer (cat no. 89900; Thermo Fisher Scientific, Inc.) for total protein extraction. The protein concentration was determined using a BCA kit (Beyotime Institute of Biotechnology) and the protein samples (40 µg) in each lane were separated with 10% SDS-PAGE. The target proteins were transferred to a PVDF membrane (EMD Millipore), which was incubated in 5% non-fat milk at room temperature for 90 min to block non-specific binding sites. Subsequently, the membranes were incubated at 4°C overnight with primary antibodies against pro-survival protein myeloid cell leukemia 1 (MCL1; rat product code ab243136; 1:1,000), Snail1 (rabbit; 1:1,000; product code ab216347) and actin (rabbit; product code ab179467; 1:5,000; all from Abcam). The membranes were probed with HRP-conjugated donkey anti-rabbit secondary antibodies (1:2,000; product code ab6802; Abcam) at room temperature for 1 h. The signals were visualized using an ECL system (Thermo Fisher Scientific, Inc.).

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.
