一般說明

该认证加标溶液®适用于从临床和诊断测试和内分泌学到运动测试的各种 GC/MS 和 LC/MS 应用。

5α-二氢睾酮（DHT）是一种类固醇激素，是天然雄激素睾酮的代谢物，通过 NADPH 依赖性酶 5α-还原酶的作用形成。它涉及广泛的疾病，例如男性秃发、良性前列腺增生、以及前列腺癌等。作为合成代谢类固醇，DHT也被用作性能增强药物，以促进肌肉生长。

應用

  • 通过液相色谱-电喷雾电离-串联质谱法（LC/ESI-MS/MS）测定睾酮和 5α-二氢睾酮在吡啶酸及其类似物的质子亲和衍生反应中的含量
  • 通过气相色谱-串联质谱法（GC-MS/MS）测定黑头鲦鱼血浆和睾丸样品中的睾酮和 5α-二氢睾酮
  • 根据世界反兴奋剂机构（WADA）的要求，采用高分辨率全扫描-电喷雾-液相色谱（HR-FS-ESI-LC）结合四极轨道阱质谱（Q/Orbitrap MS）对尿样中表睾酮、睾酮、5α-二氢睾酮、去氢表雄酮、雄酮和乙胆甾醇酮进行多残留筛选。
  • 通过稳定同位素稀释液相色谱-电喷雾电离-串联质谱法（SID-LC-ESI-MS/MS）对使用吡啶甲酸进行衍生化后的 9 种羟基雄激素及其偶联物进行定量分析

特點和優勢

  • 完全符合 ISO/IEC 17025 和 ISO 17034 认证
  • 附综合分析证书（CoA），包括稳定性、均匀性、浓度准确性、不确定性和可追溯性数据
  • 通过实时稳定性研究严格测试，以确保准确性和保质期
  • 使用合格的精密天平进行重量准备，以确保最小不确定性
  • 氩气环境下火焰密封，装入安瓿以便长期保存
  • 提供方便的 DEA 豁免格式，以提高实验室效率

In rats with dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS), repeated low-frequency electrical stimulation of acupuncture needles restores whole-body insulin sensitivity measured by euglycemic hyperinsulinemic clamp. We hypothesized that electrical stimulation causing muscle contractions and manual stimulation causing needle sensation have

5α-Reductase 2 deficiency (5ARD) is a known cause of 46,XY disorders of sex development (DSD). Traditionally, the diagnosis relies on dihydrotestosterone (DHT) measurement, but the results are often equivocal, potentially leading to misdiagnosis. We reviewed alternative approaches for diagnosis of

Questions

1–5 of 5 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Does this DHT cross react between humans and mice? cat #: D-073-1ML

    1 answer

    1. DHT exhibits cross-reactivity between humans and mice, but biological effects and responses may differ due to species-specific differences. This product is an analytical standard and is not intended for animal studies.

      Helpful?

  4. Is this suitable for cell culture?

    1 answer

    1. This product is prepared in methanol, which would be toxic to cells. Currently, there is no cell culture tested product option available. However, product A8380, the powder form, has been used successfully in cell culture applications. Please see the link below to review this product. Note the Peer Reviewed Papers section lists a number of applicable publications.

  5. hi, am I right in thinking that D-073 arrives in 1mL vials and they are to be stored long term at -70C. We only have -80C freezers, do you see that as a problem?

    1 answer

    1. The product COA (https://www.sigmaaldrich.com/certificates/Graphics/COfAInfo/fluka/pdf/cer/D-073_FE02172263.pdf) indicates on page 10 that it is okay to store this material for long term stability at -60C to -80C, so the indicated freezer/temperature should be fine.
