Nerve Growth Factor Receptor (NGFR), also known as p75, P-75NTR or CD271, is a neurotrophin receptor belonging to the tumor necrosis factor receptor family. NGFR is expressed mainly in Schwann cells and neurons, as well as a number of other non-neuronal cell types, and functions during central and peripheral nervous system development to regulate neuronal growth, migration, differentiation, and cell death. Nerve Growth Factor Receptor is also expressed in melanocytes, melanomas, neuroblastomas, pheochromocytomas, neurofibromas, neurotized nevi (type C melanocytes), and other neural crest cell or tumor derivatives. It has been suggested that NGFR may act as a tumor suppressor indicated in prostate and urothelial cancer, and Anti-Nerve Growth Factor Receptor (NGFR) is often used in adjunct with S100, to aid in the diagnosis of desmoplastic and neurotrophic malignant melanomas. Anti-NGFR is also useful as an aid in the diagnosis of breast malignancy, as the antibody labels the myoepithelial cells of breast ducts and intralobular fibroblasts of breast ducts.
M-SAN HQ – Peak performance where it matters most at physiological conditions
Medium-Salt Active Nuclease High Quality (M-SAN HQ) is a Bioprocessing Grade nuclease developed for removal of both single and double-stranded DNA and RNA at the physiological salt conditions most often used in bioprocessing and biomanufacturing workflows. M-SAN HQ allows you to directly replace Benzonase without changing your workflow.
This novel, nonspecific endonuclease is active over a broad pH range and displays optimum activity at salt concentrations between 125 – 250 mM. Due to its excellent performance at physiological conditions, M-SAN HQ can be used directly in the cell medium or the harvested supernatant without buffer adjustments. This makes M-SAN HQ ideal for the manufacturing of fragile vectors such as lentiviruses and retroviruses.
M-SAN HQ can be directly used in medium without buffer adjustments The high activity of M-SAN HQ at standard cell medium conditions leads to improved DNA clearance compared to other commonly used nucleases. In the data (see Figure 6), an over 2-fold reduction in residual DNA was achieved.
Key Benefits
Compatibility: Ideal for working with both fragile and robust viral vectors and proteins in a variety of cell media
Optimum activity: Optimization for cell media salinity allows both shorter DNA fragments and reduced incubation times.
Cost-Effectiveness: Reduced need for additional reagents and steps can lower production costs
Quality: Maintains the integrity of sensitive or labile biological molecules, ensuring a higher quality end product
Flexibility: Can be used directly in a variety of media without the need for customization
Key Features
High purity (≥ 99%)
No protease detected
Endotoxin-tested
Animal origin-free production
Supplied with extended product documentation
Adapted to use in medium without salinity adjustments
Optimal activity at physiological salinity and pH makes it ideal for DNA removal from mammalian cell media. (see Figures)
The high activity of M-SAN HQ at the physiological salinity and pH found in standard cell medium conditions leads to improved DNA clearance compared to commonly used nucleases.
Simple to Optimize in Cell Media
M-SAN HQ is uniquely formulated to excel in physiological pH conditions, offering high performance at the commonly used cell media pH of 7.4.
While other nucleases often require more alkaline environments, M-SAN HQ stands out for its adaptability and effectiveness in cell media. It’s the nuclease that truly aligns with your bioprocessing needs. (See Figure section)

Principle
Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
Advantages
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – extraction of several samples can be completed in 60 minutes by column purification method
Safe – no phenol chloroform extraction required
Sensitive – RNA can be purified at the level of PG

Storage and Stability
Buffer PHC should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under theseconditions.The entire kit can be stored at 2–8°C, but in this case buffers should be redissolvedbefore use. Make sure that all buffers are at room temperature when used.
