Hoechst 33342 is commonly used for live-cell imaging. Fixation is not required as this material is more lipophilic as compared to the Hoechst 33258. This product has not been tested specifically on oocytes, however several publication referencing this material were found in a literature search. Please see the link below to review one example:

bisBenzimide H 33342 trihydrochloride can be used to study biochemicals and reagents, fluorescent probes, labels, particles and stains, luminescent compounds and detection and wavelength index. bisBenzimide H 33342 trihydrochloride, Hoechst 33342, has been used in a study to investigate the effects of inorganic and organic arsenic compounds on human T-lymphoblastoid leukemia cells. Hoechst 33342 has also been used in a study to examine the effects of 9 calcium antagonists on ABCG2/BCRP-mediated resistance and transport in HeLa and SN-38-resistant HeLa (HeLa/SN100) cells, overexpressing ABCG2/BCRP.
Biochem/physiol Actions
Membrane-permeable, fluorescent DNA stains with low cytotoxicity that intercalate in A-T regions of DNA.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

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

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