GoodColor™ Prestained Color Protein Marker (15-120kD) contains a total of 7 purified prestained proteins ranging from 15 kD to 120 kD. The 15 kD and 70 kD bands appear in red color, while the remaining bands appear in blue color. It is suitable for use as a protein molecular weight standard in SDS-PAGE or Western blotting. It is particularly well-suited for Western blotting, as it allows for direct and clear visualization of the transfer efficiency after membrane transfer. Please note that the molecular weights are applicable only for regular Tris-Glycine gels.
The product provides two vibrant red bands (15 kD and 70 kD), which facilitate rapid and accurate identification of the protein molecular weight standard bands. Additionally, the product contains a red dye similar to bromophenol blue, which appears as a front marker in red during electrophoresis.
A total of 7 distinct bands ranging from 15 kD to 120 kD are provided, with clear bands and a relatively wide molecular weight range, making it convenient for protein molecular weight comparisons.
The prestained color protein molecular weight marker is pre-formulated in 1X SDS-PAGE sample buffer. It can be directly used after thawing and thorough mixing at room temperature, without requiring high-temperature heating or boiling. High-temperature heating or boiling is strictly prohibited.
Depending on the size of the loading wells, it is typically recommended to load 3-5 μl of the prestained color protein marker per lane. This will allow for clear visualization of protein bands during electrophoresis, after electrophoresis, or after membrane transfer.
- The prestained color protein molecular weight marker should not be heated or boiled at 100°C, and it should not be heated above 40°C. It can be directly used after thawing and thorough mixing at room temperature. Boiling for 5 minutes can cause approximately 50% of the bands to degrade or lose color.
- The prestained color protein molecular weight marker is prepared in 1X SDS-PAGE sample buffer and is not suitable for non-denaturing PAGE gels.
- The molecular weight sizes of the prestained protein molecular weight marker may vary between batches, which is considered a normal occurrence. Please refer to the accompanying manual for precise molecular weight information.
- This product is intended for scientific research purposes by professionals only. It should not be used for clinical diagnosis or treatment, food or drug purposes, and it should not be stored in residential areas.
- For your safety and health, please wear appropriate laboratory attire and disposable gloves when handling this product.
