  4. Product K4002 - Krebs-Ringer Bicarbonate Buffer, is without calcium chloride and sodium bicarbonate. In the reconstitution steps, you advice to add 1.26g sodium bicarbonate. Should we also add some calcium chloride? in which amount?

    1 answer
    1. Product K4002 - Krebs-Ringer Bicarbonate Buffer does not contain calcium. The addition of calcium is not required for osmolarity.  If you need to have calcium, you can add calcium chloride between 1.25 to 2.5 mM.  You may want to check the osmolarity and make sure it is not too high.Kreb Henseleit Buffer has 1.25 mM calcium chlorideKreb's Buffer has 2.5 mM calcium chlorideKreb' Ringer Superfusion solution contains 2.0 mM calcium chloride.Please see the attached document for different Krebs' buffer recipes.
