During development, many mutations cause increased variation in phenotypic outcomes, a phenomenon termed decanalization. Phenotypic discordance is often observed in the absence of genetic and environmental variations, but the mechanisms underlying such inter-individual phenotypic discordance remain elusive.

Questions

1–8 of 8 Questions  
  1. How much Heparin sodium salt, is used to prevent coagulation?

    1 answer
    1. It is suggested to use 15 to 30 units per mL of blood.

  2. What is the best way to sterilize Heparin sodium salt?

    1 answer
    1. Although solutions may be autoclaved at 121 °C for 5 to 10 minutes, we generally recommend sterile filtration. This is because prolonged autoclaving may have an effect on its activity.

  3. What concentration of Heparin sodium salt, can I use to inhibit RNAse activity?

    1 answer
    1. Heparin has been used at concentrations ranging from 100 to 500 μg/mL. This has been reported in the J. Biol. Chem., 248, 2095 (1973).

  4. How does the storage temperature relate to shipping conditions?

    1 answer
    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
