Application

Phenylhydrazine hydrochloride is used in the examination of tyrosine phosphorylation of Janus protein tyrosine kinase (JAKs) in the EPO-responsive normal erythroblastoid cells of anemic mice[1].

Biochem/physiol Actions

Phenylhydrazine hydrochloride causes acute hemolysis when injected intraperitoneally in to wild-type and Hp and Hx single-null mice[2]. It suppresses the horseradish peroxide (HRP) residual activity in tissue sections of animals[3].

Preparation Note

50 gm of Phenylhydrazine hydrochloride dissolves in 1 mL of water to yield a clear, very faint yellow solution.

Cyclophosphamide is widely used to treat children with medulloblastoma; however, little is known about its brain penetration. We performed cerebral microdialysis to characterize the brain penetration of cyclophosphamide (130 mg/kg, IP) and its metabolites [4-hydroxy-cyclophosphamide (4OH-CTX) and carboxyethylphosphoramide mustard (CEPM)]

Questions

1–4 of 4 Questions  

  1. 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.

  2. 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

  3. Can we store aliquots of PHZ (dissolved in PBS) in -20? How long does it remain stable? Thanks!

    1 answer

    1. This product has not been evaluated for stability in solution. Phenylhydrazine HCl solutions may decompose when exposed to light and air. There are commercially available solutions in water that are packaged in amber glass and have an approximate shelf life of 1 year at room temperature, according to manufacturers. Note that this information has not been validated.

  4. Como puedo saber la fecha de caducidad si no aparece en el CoA?

    1 answer

    1. This product does not contain an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one year warranty from the date of shipment.
