CRISPR/Cas9 is a powerful gene-editing tool that has revolutionized genetics and molecular biology research. It enables precise manipulation of DNA sequences within the genome, allowing researchers to create small animal models with specific gene modifications. CRISPR/Cas9-based gene editing in small animals typically involves the delivery of Cas9 nuclease and a guide RNA (gRNA) to the…
Sonoporation is a non-viral, non-invasive technique that uses ultrasound energy in combination with microbubbles to facilitate the delivery of genetic material into cells. This method has gained interest in small animal research due to its potential for targeted, efficient, and safe gene delivery. Mechanism: Advantages of sonoporation and microbubble-assisted transfection in small animals: Challenges and…
Polymer-based transfection reagents are composed of natural or synthetic polymers that can form complexes with genetic material, such as plasmid DNA, siRNA, or mRNA, to facilitate their delivery into cells. These reagents offer several attractive features for small animal research, which have led to their widespread use in various applications. Features of polymer-based transfection reagents:…
Nanoparticle-mediated transfection is a promising approach for gene delivery in small animals. This method uses nanoparticles, which are nanometer-sized particles made from various materials, to encapsulate or complex with genetic material and deliver it into cells. Nanoparticles can protect the genetic material from degradation, improve cellular uptake, and provide targeted delivery. Materials: Different materials can…
Viral vectors are engineered viruses that can deliver foreign genetic material into host cells. They are widely used for gene delivery in research and gene therapy applications due to their high transduction efficiency and ability to infect a wide range of cell types. There are several types of viral vectors, each with unique properties, advantages,…
Electroporation is a technique that uses electric fields to introduce foreign genetic material into cells by creating temporary pores in the cell membrane. In small animal research, electroporation can be employed both in vitro (cell culture) and in vivo (directly in the animal). Here, we will focus on in vivo electroporation in small animals and…
Lipid-based transfection reagents are one of the most popular and widely used methods for introducing foreign genetic material into cells. They are composed of cationic lipids, which have a positively charged head group and a hydrophobic tail, allowing them to interact with the negatively charged genetic material (e.g., DNA or RNA) and the cell membrane….
Transfection is the process of introducing foreign genetic material, such as DNA or RNA, into cells to study the function and regulation of genes. This technique is widely used in small animal research to understand gene function, develop therapies, and create genetically modified organisms. There are various methods available for transfecting small animals, each with…
Epidemiology is the study of the distribution and determinants of health and disease in populations. This field plays an essential role in public health, informing decisions about prevention and control measures for a wide range of health conditions. Epidemiologists use a variety of methods to study patterns of disease occurrence and transmission. These methods include…
Immunology is the study of the immune system and its interactions with pathogens, foreign substances, and abnormal cells. The immune system plays a critical role in protecting the body from infection and disease, and immunology has contributed to numerous advances in medicine, including the development of vaccines and immunotherapies. The immune system is made up…
