A transparent, optically clear, DMSO resistant, non-tacky film which adheres only when pressure is applied. It is non-pierceable and peelable. Clear plastic, reflective, glossy on the top. Very thin and light and doesn’t crease easily.
Detail
Overview
A transparent, optically clear, DMSO resistant, non-tacky film which adheres only when pressure is applied. It is non-pierceable and peelable. Clear plastic, reflective, glossy on the top. Very thin and light and doesn’t crease easily.
Crystal clear seal specifically developed for optical applications, particularly qPCR
Non-sticky when removed from the packaging aiding with handling when using gloves
When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate – the rest of the seal area above the wells remains optically clear

Overview
All shipping requirements in one convenient mailer
Leak-proof biohazard bags with adsorbent pads for enhanced safety
Matches the standards of OSHA as well as the IATA regulations
Norgen’s Shipping Accessories provides a safe and convenient tool for shipping non-infectious biological specimens. The accessories are contained in individual SHIP TO envelopes that are used for shipping of both the accessories as well as the individual sample collection device to the donor/user.
Each SHIP TO envelope contains:
A Biohazard Specimen Bag with absorbent pad;
A Bubble Envelope labeled as “Exempt Human Specimen”;
2 blank labels;
Shipping Instructions
The Biohazard Specimen Bag is a sure-seal zipper bag to hold the collected specimen and protect against accidental spills. The bag contains an absorbent pad that can adsorb up to 4 mL of liquid and meets current labeling requirements of OSHA standard 29CFR1910.1030 regarding biohazard symbols. The Bubble Envelope is used as a RETURN envelope for the donor/user to ship the collected sample back to the lab for analysis. The user will first place the collected sample into the Biohazard Specimen Bag, and then place the Biohazard Specimen Bag into the Bubble Envelope. The Bubble Envelope protects against moisture and punctures, and facilitates smooth insertion with convenient self-sealing closure. The 2 labels are used for both the outer SHIP TO envelope and the RETURN bubble envelope. The SHIP TO label will be filled out to contain the mailing information of the donor and the RETURN label will be filled out to contain the address to which the sample should be returned. The labels can be supplied as sheets together with the word template file for ease of printing. Norgen’s Shipping Accessories match the regulations of the International Air Transport Association (IATA).

Bioprocessing with Salt Active Nucleases – High Salt Conditions
OverView
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.
Host Cell Lysis: Facilitates efficient lysis of host cells in high-salt conditions, optimizing the harvest of both secreted and non-secreted viral vectors.

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.
SAN HQ ELISA kit is developed for the detection and quantification of SAN HQ and SAN HQ GMP. The kit is designed as a classical sandwich ELISA, with two monoclonal antibodies specific towards SAN HQ nuclease (fig 6).
Features
Sensitive: 0.4 – 25.6 ng/ml
Precise: RSD ≤ 15%
Accurate: 100% ± 15%
Stability: 12 months when stored between +2°C to +8°C
