19063 Buffer Qg (250 Ml)

The **19063 Buffer QG (250 ml)** is likely a type of buffer solution used in various laboratory applications, particularly for DNA extraction or purification. It appears to be part of a set or product line related to genomic DNA handling. Based on the typical naming conventions for buffer solutions in DNA purification kits, **Buffer QG** could refer to a **buffer solution used for the binding or washing steps** during DNA isolation, particularly for processes like **column-based DNA purification**.
### Some of the Possibilities of the "Buffer QG (250 ml)": 1. **Binding/Washing Step Buffer**:
- It may be used in DNA extraction protocols, especially for washing or binding DNA to a column or other solid-phase during purification.
It typically removes contaminants like proteins, lipids, and other impurities from the DNA sample in conjunction with other buffers. 2. **Components**:
- **Buffer QG** often contains **guanidine salts**, which help denature proteins and other contaminants while keeping the DNA intact.
- **Chaotropic agents** in such buffers are commonly used to disrupt the structure of proteins and other cellular components, facilitating the binding of DNA to silica columns or magnetic beads.
3. **pH & Composition**:
- The pH and specific salts in the buffer are often optimized to promote efficient DNA binding while ensuring that unwanted contaminants are washed away during the purification process.
### Typical Use Cases:
- **DNA Purification**: It would typically be used in the purification of genomic DNA, which could then be used for downstream applications like **PCR, sequencing, or cloning**.
- **Lab Protocols**: These are typically included in kits that are made to extract and purify genomic DNA from tissues, blood, or cells to a high standard. - **Sample Preparation**: Ensures that DNA is free from contamination before it is used in experiments.
Since **Buffer QG (250 ml)** is a component of a larger genomic extraction system, it typically comes with instructions for use in a specific kit. The product datasheet frequently contains specific details, such as the pH or composition. I would suggest visiting the manufacturer's website or getting in touch with the supplier for a comprehensive description of the product, which should include the precise components and application instructions. It may be part of a DNA extraction kit or from a brand like **Qiagen**, **Thermo Fisher**, or another laboratory reagent provider.
