Product Introduction
Background
L-Ascorbic acid-2-phosphate trisodium salt (Asc-2P) is a stabilized vitamin C derivative with antioxidant activity. It protects cells from oxygen radical damage, inhibits apoptosis, promotes the production of hepatocyte growth factor (HGF), facilitates the expression and formation of collagen, and serves as an alkaline phosphatase ALP catalytic substrate.
Ingredient Statement
With
• Ultrapure water Dissolvent
Matters Need Attention
1. This product is only used for scientific research or further research, not for diagnosis and treatment.
2. This product was sterilized by 0.1 μm filtration and can be used directly after melting.
3. It is necessary to pay attention to the aseptic operation and avoid the contamination.
4. Before using, the product should be thawed at 2-8℃ and shaken thoroughly
repeated freeze-thaw cycles are not advised.
5. If precipitation happens after thawing, the contents can be resuspended by pipetting or vortex mixing. After incubating the solution at 37℃ for 20 to 30 minutes or letting it stand at room temperature for about an hour, check to see if the precipitate dissolves as intended. If the product dissolves completely, it can be used as usual.
6. This product is a concentrated solution and should be diluted prior to use as required.
7. The product should be used within a month if stored regularly at 2-8℃. Keep in a frozen state at -5~-20℃ for extended storage. Long-term storage at room temperature or between 2-8℃ is not recommended. When lesser amounts are required, aliquoting is advised to prevent repeated freeze-thaw cycles.

FAQs

Q:1 Can the L-ascorbic acid-2-phosphate trisodium salt solution (1 M) serve as a substitute for vitamin C?
AnswerThis reagent is a stable, long-acting derivative of vitamin C and provides comparable antioxidant effects. In general, it is more stable than conventional vitamin C (ascorbic acid). However, for certain cell experiments requiring rapid onset, such as studying the direct cytotoxicity of vitamin C on cancer cells at high concentrations (pro-oxidant effect) or investigating acute antioxidant responses, regular vitamin C may be more suitable due to its faster activity. In some cases, such as with primary cells or cells with low alkaline phosphatase (ALP) activity (which can be assessed by Western blot), conventional vitamin C is preferred to avoid insufficient conversion by tissue non-specific alkaline phosphatase (TNAP). The L-ascorbic acid 2-phosphate trisodium salt (catalog number PB180606) was originally developed for long-term cell culture applications such as organoid culture. You may choose the appropriate form based on your experimental goals.

Q:3 If I use Pricella's B-27 (50x) to prepare Neurobasal + 2% B-27(50x), how do I prepare it? Is it 2% based on 50x or 2% based on 1x?
Answer2% based on 50×. For example, prepare 100 mL medium means adding 2 mL B-27(50×), the concentration is 2%.
