Lnjnbio Magnetic Beads for Animal Tissue Total RNA Extraction Kit 231002

(Magnetic Bead Method)

【Product Introduction】

This kit uses a unique separation magnetic bead and buffer system to extract RNA from animal tissues, and the whole process is easy to operate, which is especially suitable for automated nucleic acid extraction platforms. The extracted nucleic acids have high yield, high purity, stable and reliable quality, and can be applied to various downstream molecular biology experiments.

【Product advantages】

1. Easy and fast: Samples are directly lysed without liquid nitrogen grinding, and high-quality RNA can be obtained in less than 1 h without long incubation.
2. Safe and non-toxic: No organic reagents such as phenol/chloroform are required.
3. Wide range of applications: Suitable for a wide range of animal tissues, soft tissues (e.g., liver, kidney), adipose tissue (e.g., brain), and fibrous tissues (e.g., muscle), as well as more difficult samples such as mouse tails, shell tissues.
4. High-throughput: Magnetic stand manual extraction can be selected or nucleic acid extractor can be used to achieve automated, high-throughput operation.
5. Efficient extraction: Biomagnetic beads have a small size effect and surface effect, which can efficiently extract nucleic acids and meet the requirements of nucleic acid extraction from rare samples and trace biological samples.

【Application area】

Basic molecular biology studies

It is suitable for extracting high-quality total RNA from complex animal tissues such as liver, brain, muscle and muscle for gene expression analysis (e. g., qRT-PCR, RNA-seq), transcriptomic studies and exploration of non-coding RNA function. It is especially suitable for processing samples rich in lipids or collagen, and magnetic bead-specific binding to RNA can effectively remove polysaccharides, proteins and other disruptors.

Disease mechanism and diagnostic studies

In oncology, neurodegenerative diseases, etc., they were used to extract RNA from pathological tissue samples to analyze disease-related gene expression profiles. Such as cancer studies detecting mRNA variants in cancerous tissues, or dysregulation of miRNA in neural tissues.

Drug development and safety evaluation

Supporting the assessment of the effect of drugs on gene expression in target organs in pharmacodynamic studies and the expression detection of genes related to drug metabolism (e. g., CYP450 family) in toxicology experiments.

Veterinary medicine and agricultural biotechnology

It is used for the diagnosis of livestock and poultry diseases (such as African swine fever virus detection), the verification of gene editing effect in the construction of transgenic animal models, and the functional analysis of genes related to the growth and development of economic animals.

Species identification

Combined with species-specific RNA markers, which can be used for source identification of biological samples. With easy operation (automation), high purity (A260 / A280> 1.9) and good integrity (RIN 8), this technology has become an important supporting platform for modern molecular experiments.
