✨ core advantage

one ️⃣ High purity, low interference: A purity of over 99.5% far exceeds the industry standard (most competitors have a purity of 85% -95%), greatly reducing the interference of impurities on experimental results (such as cytotoxicity and non-specific binding), especially suitable for experiments with high sensitivity requirements (such as qPCR, Western Blot).

two ️⃣ Full process quality control: From raw material synthesis to finished product packaging, through 12 quality inspection checkpoints (including HPLC, LC-MS, sterility testing, etc.), detailed COA (Certificate of Analysis) is provided for each batch, with traceable data and more reliable experimental results.

three ️⃣ Strong adaptability: Not only does it support conventional solvent dissolution (such as DMSO, ethanol), but it can also provide customized sterile solutions (concentration 1mM-100mM) according to needs, which can be directly used for cell experiments, eliminating the tedious steps of self preparation.

four ️⃣ Worry free after-sales service: provide a professional technical support team to answer questions about experimental design, storage conditions, etc; If there is a quality issue with the received product, we will respond with a return or exchange within 72 hours.

❓ Purchase Questions&Answers

Q1：17 β - estradiol sustained-release tabletsWhat is included in the purity testing report (COA)?

A: COA includes HPLC purity spectra (area normalization method), LC-MS molecular weight validation, endotoxin detection results, heavy metal residue data (lead, mercury, arsenic, etc.), and production batch information to ensure traceability at every step.

Q2: If sterile solution is required for the experiment, can you customize it?

A: Okay! We support aseptic filling services (0.22 μ m membrane filtration) and offer commonly used concentration options ranging from 1mM-100mM. Please note your requirements when placing an order.

Q3: What should be noted for long-term storage?

A: It is recommended to store the packaged solution in the dark at -20 ℃ (to avoid repeated freezing and thawing). The dissolved solution should be refrigerated at 4 ℃ and used up within one month (refer to the instructions for details).

Q4: Is it suitable for in vivo animal experiments?

A: The endotoxin content of SE-121 is ≤ 0.25 EU/mg (much lower than the requirement of ≤ 5 EU/mg for in vivo experiments), and the impurity content is strictly controlled. It can be used for subcutaneous/intraperitoneal injection or gavage experiments in model animals such as rats and mice (specific dosage needs to be referred to in the literature).

Q5: Can small batch purchases (such as 0.18mg) be shipped?

A: Okay! We support a minimum order quantity of 0.18mg, with regular logistics (SF/JD) shipping within 48 hours. Remote areas can be negotiated.

Q6: What are the advantages compared to other brands of 17 β - estradiol?

A: In addition to high purity and strict quality control, we also provide a free "experimental protocol reference package" (including cell culture concentration recommendations, animal model dosage, etc.) to help beginners quickly get started.

Q7: Will it degrade during transportation?

A: The product is transported in an insulated box and ice packs (with additional dry ice added in summer) to ensure a temperature of ≤ -15 ℃ throughout the entire process. After testing and transportation, there is no significant change in purity (a transportation stability report can be provided).

Q8: How long is the shelf life?

A: The unopened powder has a shelf life of 2 years (below 25 ℃), and it is recommended to use up the dissolved solution within 1 month (subject to COA labeling).
