SKU: 3e49726e6e46 Category: Proteinase K Reagent Tags: For Histology, For Research, Proteinase K

Storage Temperature:

Stored at room temperature for three years.

Product Introduction:

Proteinase K is a non-specific serine protease, and the RNase and DNase activities have been

removed after purification. Proteinase K is active in the presence of SDS or urea as well as in a

wide range of pH, salt concentration and temperature, and can be increased in 1% SDS.

Proteinase K is widely used in the preparation of pulsed electrophoresis chromosomal DNA,

western blot and genomic DNA. The working concentration is usually 50-500g/mL, and the

specific working concentration is determined according to whether the buffer solution

contains SDS, urea, pH, temperature and other factors.

Product Nature:

RNase and DNase are not included;

Specs:1g;

Active in denaturant, such as urea and SDS;

Active in metal chelators, such as EDTA;

Active in a wide pH range (pH 4-12.5), the best pH range is pH 7.5-8.0;

Active in a wide range of temperature, generally operating temperature range of 50℃-65℃;

ddH2O can be dissolved;

7.Enzyme activity value: ≥30 U/mg Lyophilized powder.

Method of Inactivation:

After heating at 95℃-98℃ for 10 min, or adding PMSF or DFP inhibitor into the reaction

system, it was deactivated.

Remark:

The general storage concentration is 10-20 mg/ml to avoid repeated freeze-thaw;

Ca2+ can increase the thermal stability of protease K.

Special Requirements: Medical equipment often has specific needs, such as temperature control or shock absorption. For example, certain medications must remain at a specific temperature throughout the supply chain. This may require insulated containers, refrigerated vehicles, and specialized warehousing.
Custom Packaging: Custom packaging solutions are essential for medical equipment. A professional crating company can provide protective packaging tailored to the unique requirements of each product. This can include foam packaging die-cut to the exact shape needed for the product.
Reusable Packaging: For regular shipments, reusable packaging can be a cost-effective and environmentally friendly option. These crates can be assembled and disassembled without tools and can be fully customized.
International Shipping: When shipping internationally, it's important to be aware of customs regulations. Failure to comply can result in delays, returns, or fines. Professional shipping companies can help obtain the necessary permits and documentation.
Insurance and Tracking: Given the high cost and critical nature of medical equipment, insurance is essential. Tracking can also provide peace of mind and help prevent loss.
