Acetic Acid Assay Kit (Acetate Kinase Manual Format)

Introduction

Magnetic bead nucleic acid purification technology uses nano or micron superparamagnetic material as the matrix, generally black ferric oxide or yellowish brown ferricoxide as the magnetic material. The surface of bead is coated with appropriate functional groups, which can adsorb nucleic acid. Magnetic beads commonly used for nucleic acids, containing carboxyl groups, hydroxyl groups, or silicon groups. Silicon-based magnetic beads are the most common, and its principle of adsorbing nucleic acid is consistent with the classical glass milk purification technology or glass fiber filter membrane purification method. Magpure particle is a kind of polydisperse fast speed silica magnetic beads. The core is ferricoxide, accounting for 50%, and the surface coating is silica, accounting for 50%. The product can be used for plasmid extraction, gel DNA recovery, product purification, genomic DNA and RNA extraction, and viral nucleic acid extraction.

Principle

Highsalt mediated binding: in the solution containing 2-4M guanidine isothiocyanate, Magpure particles can selectively recover DNA molecules, and impurities such as protein polysaccharides are not adsorbed.

Alcohol mediated binding: in the solution containing guanidine salt and alcohol (>25%), Magpure particles can selectively recover DNA/RNA molecules, and proteins and other impurities are not adsorbed.

After biological samples are treated with digestive solution or lysis Buffer, DNA/RNA is released from cells, organelles and protein complexes (ribosomes and nucleosomes) into reagents. After Magpure particles and binding solution are added, DNA/RNA is adsorbed to the surface of Magpure particles to form DNA/RNA bead complex. Under the action of the magnetic field, the magnetic beads are separated and collected, and the impurities such as protein are removed with the waste liquid. After two or three steps of further cleaning, the DNA/RNA magnetic bead complex is resuspended in sterilized water or TE buffer, and the DNA/RNA falls off from the surface of the magnetic beads, so as to achieve the purpose of purification.

• The MagPure magnetic-particle technology combines the speed and efficiency of silica-based DNA purification with the convenient handling of magnetic particles. DNA binds to the silica surface of the magnetic particles in the presence of a chaotropic salt. DNA bound to the particles is then efficiently washed, considerably improving the purity of DNA. High-quality DNA is eluted. The automated purification procedure completely removes enzymes, nucleotides, and other contaminants and inhibitors. Purified DNA is suitable for direct use in downstream applications, such as sequencing and microarray analysis.

For SAN HQ, SAN HQ ELISA Kit, and now SAN HQ GMP

SAN HQ GMP is biochemically identical to SAN HQ but produced under GMP conditions.

Applications

• Purification of biologics from residual nucleic acids in biopharma manufacturing
• Purification of recombinant proteins and enzymes for research and diagnostic use
• Removal of unwanted nucleic acids contamination in molecular biology reagents in challenging conditions
• Reduction of viscosity in biological samples during production and automation
• Vaccine manufacturing and viral vector preparation
• DNA removal in high-salt lysates

SAN HQ  – Peak performance at high salt conditions

Salt Active Nuclease High Quality (SAN HQ) is a Bioprocessing Grade nuclease developed as the most efficient solution for removal of both single and double stranded DNA and RNA at high salt conditions. 

This nonspecific endonuclease has peak activity at salt concentrations between 400 – 700 mM (Fig. 1)

Non-enveloped viruses like Adenoviruses and Adeno-Associated Viruses (AAV’s) are inherently more robust with two distinct advantages: 1) They exhibit higher tolerance to additives like salt and detergents and 2) their production often involves the lysis of host cells, allowing for harvesting non-secreted vectors. 

For Adeno-Associated Viruses (AAVs), which are often harvested from crude cell lysate, the high salt tolerance of SAN HQ is particularly beneficial. Salt is typically added to such lysates to reduce viral aggregation, facilitating more effective nuclease action to digest residual DNA.

SAN HQ’s is engineered for optimum activity in these high salt environments ensuring that you achieve unparalleled DNA removal without compromising the integrity of these robust viral vectors.

Key Benefits

• Optimized Residual DNA Removal: Ensures efficient degradation of residual DNA in high-salt conditions, meeting stringent quality requirements for biologics and vaccines.
• Boosted AAV Vector Purification: Enhances the purification process for adeno-associated viral vectors in high-salt conditions, improving quality and yield.
• Streamlined Workflow: Eliminates the need for desalting stages, simplifying the bioprocessing protocol and saving time and resources.
• Enable High-Throughput Processes: Facilitates scale-up and automation by working effectively in high-salt environments, increasing operational throughput.
• Potential Surge in Virus Yield: Operates under conditions that may boost the titer yield of AAV production, potentially enhancing overall viral yield.
• Economized Enzyme Usage: Reduces the need for excess enzyme and additional process adjustments, resulting in significant cost savings.
• Minimized Risk of Process Disruptions: Offers reliable performance in various high-salt bioprocessing conditions, reducing the likelihood of disruptions due to enzyme inhibition.
• Reliability: Provides consistent enzyme activity in challenging high-salt conditions, adding a layer of predictability and dependability to your operations.
• Broader Applicability: Versatile enough to be used in a wide range of viral vector systems, expanding your research and production capabilities.
• Enhanced Viral Stability: High-salt levels stabilize viral vectors, and SAN HQ operates effectively in these conditions, maintaining high yield and quality.

The Challenge in Removing Host Cell Chromatin Impurities 

In bioprocessing, the primary role of a nuclease is to efficiently digest and fragment host-cell DNA into sufficiently small pieces, facilitating its removal during downstream processing. While most nucleases can effectively degrade naked DNA into tiny fragments under optimal conditions—as demonstrated by M-SAN HQ and SAN HQ, which can digest dsDNA into fragments smaller than 6 nt—the reality in bioprocessing is more complex. (See fig. 5)

The DNA targeted for removal often exists as chromatin, embedded in a complex matrix containing remnants of the lysed host cell as well as large amounts of the therapeutic product.The product may or may not have an affinity for the chromatin you aim to remove.

High salt is often applied to mitigate issues like aggregation. The real challenge lies in a nuclease’s ability to efficiently fragment chromatin under these more complicated, high-salt, conditions—not merely degrading naked DNA under ideal circumstances.
