Just as machines experience friction, so do our bodies as organs move and function. It also needs lubrication to keep everything running smoothly. Here is where mesothelium comes into play. It is a thin, protective layer of specialized cells that lines the internal organs and body cavities.

It acts as a slippery, friction-reducing membrane that helps organs to glide effortlessly against each other during everyday activities, such as breathing, digestion, and heartbeat. It also plays a crucial role in protecting organs from infection, injury, and inflammation.

The mesothelium is commonly found in several areas of the body:

However, exposure to asbestos, chronic inflammation, injury, infection, toxic chemicals or radiations, aging and cellular stress can become lodged in the mesothelium. Over time, these fibers cause inflammation, scarring, and DNA damage in mesothelial cells. This chronic irritation can lead to abnormal cell growth and eventually result in mesothelioma.

Mesothelioma is a rare and aggressive cancer that primarily affects the lining of the lungs (pleura) and, in some cases, the abdomen (peritoneum). Despite medical advances, mesothelioma remains challenging to diagnose and treat effectively due to its long latency period and non-specific symptoms.

So, people, especially those who are usually exposed to asbestos, should regularly get their blood samples checked for early diagnosis of mesothelioma. Researchers look for molecular markers, such as CALB2, to detect mesothelioma.

CALB2, also known as calretinin, is a calcium-binding protein that belongs to the EF-hand family. It is mainly found in specific neurons and mesothelial cells. Calretinin helps:

Because of its selective expression in mesothelial cells, CALB2 has become a valuable marker that helps identify mesothelial origin in tumor diagnostics.

In normal tissue, calretinin expression is limited to mesothelial cells, certain neurons, and some endocrine tissues. However, in tumor tissue, CALB2 expression is notably high in malignant mesothelioma. This makes it a distinct marker that helps differentiate mesothelioma from other cancers, especially adenocarcinomas.

Researchers use the anti-CALB2 antibody to detect calretinin protein expression with high specificity and sensitivity.

Anti-CALB2 polyclonal antibodies are laboratory-made antibodies designed to detect and bind specifically to CALB2 protein. Since it plays a vital role in calcium signaling and is a key biomarker for mesothelioma, it is widely used for research. Here is how these antibodies help:

Diagnosing mesothelioma can be difficult. Its symptoms, like chest pain, shortness of breath, or fatigue, are very similar to other lung diseases. Also, under a microscope, mesothelioma cells can look like other cancer types, especially adenocarcinoma of the lung.

However, anti-CALB2 antibodies attack to CALB2. If the sample "lights up" during testing, it means the cells are producing calretinin -- a clear sign that they are mesothelial in origin.

So, researchers can use this test to differentiate mesothelioma from other lung cancers. It improves accuracy in diagnosis and ensures patients get the right treatment plan.

Researchers use anti-CALB2 polyclonal antibodies in laboratory techniques like immunohistochemistry (IHC), Western blotting, and ELISA.

These methods together give researchers a clear picture of how CALB2 behaves in healthy versus cancerous tissues.

Researchers also use anti-CALB2 antibodies to understand what calretinin actually does in cancer cells. CALB2 regulates calcium inside cells, and calcium is vital for cell communication and growth.

In mesothelioma, changes in CALB2 levels can affect how cells:

By using these antibodies, scientists can study whether calretinin supports cancer growth or helps control it. This helps identify new therapeutic targets that may block or alter CALB2's activity to slow tumor growth.

The Anti-CALB2 antibody has become a powerful tool in mesothelioma research. It not only helps in accurate diagnosis but also deepens our understanding of how this cancer develops and behaves. By detecting the calretinin (CALB2) protein, researchers can distinguish mesothelioma from other cancers, study its molecular pathways, and even explore new ways to detect it early.

However, before using CALB2 antibodies for your research, make sure they are sourced from a trusted source. Otherwise, you may have to compromise on your results!
