Horseradish peroxidase hrp labeled secondary antibody

Manufactured by Elabscience

Horseradish peroxidase (HRP) labeled secondary antibody is a type of enzyme-linked antibody. It is used as a detection reagent in various immunoassay techniques, such as Western blotting, ELISA, and immunohistochemistry. The HRP enzyme catalyzes a colorimetric or chemiluminescent reaction, allowing for the visualization and quantification of target proteins or molecules.

The tissue was lysed, and protein was extracted by radioimmunoprecipitation (RIPA) cleavage buffer (Solarbio, Beijing, China). The concentration of proteins was determined by a BCA kit (Elabscience). The separation gel and concentrated gel were prepared and sampled according to the determined concentration, then transferred to the polyvinylidene fluoride (PVDF) membrane after electrophoresis and sealed with 5% skimmed milk powder for 1 hour. Primary antibody was added to the PVDF membrane and incubated overnight at 4℃ (Table 1). The antibodies used were IL-6 (AffinityBiosciences), TMEM100 (Origene) and ß-actin (Elabscience). After overnight incubation, the PVDF membrane was incubated with horseradish peroxidase (HRP) labeled secondary antibody (Elabscience) for 1 hour, and then the luminescence was visualized by ECL kit (Elabscience). The obtained image was analyzed using a development device (Odyssey ® XF).

Protein Extraction and Western Blot Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Proteins were extracted by lysing tissues with radioimmunoprecipitation (RIPA) lysis buffer (Solarbio, Beijing, China) containing 1 mM phenylmethanesulfonyl fluoride (PMSF). The concentration of extracted protein was determined with a bicinchoninic acid (BCA) kit (Solarbio, Beijing, China). Protein and loading buffer were mixed at a ratio of 4 : 1 (V/V) and boiled at 99°C for 10 min. Separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and transferred to PVDF membrane. PVDF membranes were blocked with 5% nonfat dry milk at room temperature. Membranes were then incubated with primary antibodies overnight at 4°C (Table 2). After overnight, the membrane was incubated with horseradish peroxidase (HRP)-labeled secondary antibody (Elabscience) for 1 hr, and then the ECL kit (Elabscience) was used for luminescence observation. The acquired images were analyzed using a developing instrument (Odyssey® XF).

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.
