Welcome to PreCrack! Recently, Scientists has developed the most powerful antivenom for snakes. But there is a distinct differ in their making process. Generally or more traditionally, the antivenom is developed by testing or using the animals as platform or injecting the venom to the animals, but this time, the most powerful antivenom in the world (95Mat5), is made by injecting it to the humans and  collected the antibodies that human-bodies do produces.

Why is 95Mat5 in the news?

95Mat5 is making headlines due to its amazing significance in antivenom development. This newly created antidote offers a powerful solution for neutralizing cobra venom, marking a departure from traditional methods reliant on animal antibodies.

Background of Snakebites in the World

Snakebites are a big problem worldwide, especially in places where venomous snakes live. Every year, more than 100,000 people die from snakebites, and about 400,000 are left with lasting disabilities. Continents like those in Africa and Asia, where many people live in poverty, are hit the hardest.

What is 95Mat5?

95Mat5 is refers to a synthetic antibody with the potential to be a game-changer in snakebite treatment. Here’s a breakdown of what it is:

1. Type: Synthetic Antibody – Unlike traditional antivenoms made by injecting horses with snake venom, 95Mat5 is created in a lab.
2. Target: Neurotoxins – These are poisonous components in snake venom that attack the nervous system, potentially leading to paralysis and death.
3. Specificity: Broadly Neutralizing – A key advantage of 95Mat5 is its ability to target a common element across various elapid snakes, including cobras, mambas, and kraits. Traditional antivenoms typically target a specific snake species.

Different Types of Venom in India

India is home to a rich variety of venomous snakes, with over 60 species. These snakes can be broadly categorized based on the type of venom they possess. Here are the three main types of venom found in snakes in India:

1. Neurotoxic Venom

This type of venom primarily targets the nervous system, disrupting communication between nerves and muscles. Symptoms of a neurotoxic bite can include paralysis, difficulty breathing, and even death if left untreated. Common krait (Bungarus caeruleus) and Indian cobra (Naja naja) are examples of snakes in India with neurotoxic venom.

 
2. Hemotoxic Venom

Hemotoxic venom attacks the circulatory system, damaging blood cells and tissues. This can lead to internal bleeding, swelling, and tissue necrosis (death of tissue). Russell’s viper (Daboia russelii) and Saw-scaled viper (Echis carinatus) are some of the vipers in India that inject hemotoxic venom.

3. Cytotoxic Venom

Cytotoxic venom targets and destroys cells at the site of the bite, causing severe pain, inflammation, and tissue death. While not as common as neurotoxic and hemotoxic venom, some sea snakes found in India, like the Indian Sea Krait (Hydrophis platurus), have cytotoxins in their venom.

Traditional Way to Make Antidote of Venom

This is the traditional way to make antidote of venom. We have explained it step by step:

1. Venom Collection: Venom is extracted from venomous snakes using specialized techniques to minimize harm to the snakes.
2. Animal Selection: Large animals, such as horses or sheep, are selected as the hosts for producing antibodies against the venom.
3. Venom Inoculation: The selected animals are injected with small, gradually increasing doses of venom over a period of time. This process stimulates the animal’s immune system to produce antibodies against the venom.
4. Antibody Production: As the animals are repeatedly exposed to venom, their immune systems generate antibodies specific to the venom’s components.
5. Blood Collection: Once a sufficient antibody response has been generated, blood is collected from the animals.
6. Serum Separation: The blood is centrifuged to separate the serum, which contains the antibodies, from the cellular components.
7. Serum Fractionation: The serum is subjected to fractionation techniques to isolate the antibodies from other serum proteins.
8. Purification: The isolated antibodies are purified to remove any remaining contaminants and ensure the antivenom’s safety and efficacy.
9. Standardization: The potency of the antivenom is standardized through testing to ensure consistent effectiveness in neutralizing venom.
10. Formulation: The purified and standardized antibodies are formulated into a final product suitable for therapeutic use, such as freeze-dried vials or liquid solutions.
11. Packaging and Distribution: The final antivenom product is packaged and distributed to healthcare facilities where it can be administered to snakebite victims.
