  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What solvents can be used to dissolve Benzamidine, Product 12072?

    Based on our experience with this compound in quality control, we would expect it to be soluble in methanol (0.5g in 10mL of methanol).

  6. The buffer preparation protocol calls for benzamidine. Should I use the free base or the hydrochloride hydrate salt?

    It is possible that either the benzamidine or the benzamidine hydrochloride hydrate could work for your application. The major difference will be that the benzamidine hydrochloride hydrate (Product No. B6506) is expected to dissolve easier in aqueous solutions. Neither Product 12072 nor the salt Product B5606 is molecular biology, cell culture or biotechnology certified, so their performance once dissolved is likely to be similar.

  7. What is the solution stability of Benzamidine, Product 12072?

    Sigma-Aldrich does not perform formal solution stability testing on this material; however, it is expected to be sensitive to oxidation. It is recommended to prepare solutions fresh for each use.

Proliferating cells actively control their size by mechanisms that are poorly understood. The unicellular green alga Chlamydomonas reinhardtii divides by multiple fission, wherein a 'counting' mechanism couples mother cell-size to cell division number allowing production of uniform-sized daughters.
