Nota de preparación

Below 35-40 °C, gelatin swells in and absorbs 5-10 times its weight of water to form a gel. Gelatin is more soluble in hot than in cold water. If visible floaters or cloudiness is evident, solution may be warmed in 45°C water bath for 10 minutes to achieve clear, colorless solution.

We have previously shown that DNA immunization with PspA (pneumococcal surface protein A) DNA is able to elicit protection comparable to that elicited by immunization with PspA protein (with alum as adjuvant), even though the antibody levels elicited by DNA

CD47 acts as a "don't eat me" signal that protects cells from phagocytosis by binding and activating its receptor SIPRA on macrophages. CD47 suppresses multiple different pro-engulfment "eat me" signals, including immunoglobulin G (IgG), complement, and calreticulin, on distinct target

Complement (C) can be activated during malaria, C components consumed and inflammatory mediators produced. This has potential to impair host innate defence. In a case-control study, C activation was assessed by measuring serum haemolytic activity (CH50), functional activity of each

Questions

1–2 of 2 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
