  • Biology-Online • View topic - Calcium vs magnesium binding
    dialysis circuit the patient will lose both Ca and Mg What I have been unable to determine from the literature is what the relative binding affinities are for each ion The reason I need to know is that I want to chelate free calcium from the typical physiologic level of 1 100 1 400 nmols down to a specific level roughly 350 400 nmols and no further I have a given volume of bone marrow aspirate and I know the starting concentrations of Ca and Mg all I need to know is how much citrate to add to chelate the desired amount of Ca to yield the desired concentration The problem is that I don t know how aggressively citrate binds to Ca vs Mg Obviously the part that binds to Mg will be unavailable to bind Ca so I need to add somewhat more than the theoretical amount for Ca alone but if Mg is a weak competitive binder I don t want to add too much citrate and drop my Ca concentration too far I could figure this out by experimentation but obtaining fresh bone marrow samples to play with is not a trivial procedure nor inexpensive Does

  • Biology-Online • View topic - Coagulation, is factor IX a required part of external path?
    wall of the blood vessel Only activated factor VII is needed in the extrinsic pathway bypassing factors XII XI IX and VIII So first it states factor IX is part of the external path Factor VIIa activates coagulation factor IX to IXa and then immediately afterward it states that factor IX is bypassed in the external path Wut Factor VII is the activator of factor X in the external pathway as made clear by second image but does it depend on factor IX or not The image doesn t indicate that but why does the text say so Second quandary What does the arrow in the first image from activated factor VIIa connecting to intrinsic pathway factor IX activation mean Does it mean that activated factor VII VIIa is required to activate factor IX along with calcium Ca and factor XIa or does it mean something else Begin chronologically scanned textbook text and images Reply with quote Hodag Hodag Posts 7 Joined Tue Dec 15 2009 10 19 pm Sat Dec 05 2015 7 52 pm The answer is yes Factor IX is required Let me see if I can explain it better than the book did There are two ways to activate X to Xa after which all the steps are the same hence the name Common Cascade The contact activation cascade needs four components to activate Factor X Factor VIIIa Factor IXa Phospholipids Ionized calcium formerly Factor IV The tissue factor cascade also needs four components to activate Factor X Factor III tissue factor Factor VIIa Phospholipids Ionized calcium formerly Factor IV Since Factor III is required to activate VII to VIIa is must already be present by implication but you really do need all four components to get the job done To say Factor VIIa alone is

  • Biology-Online • View topic - Definition of receptor and enzyme inhibitor assays
    the assays in question For receptor assay I understand that there are examples like progesterone receptor assay and estrogen receptor assay and that they are for the testing of the presence of a receptor and its amount So they are also ligand binding assay LBA right Since by definition from wikipedia LBA is an assay or an analytic procedure whose procedure or method relies on the binding of ligand molecules to receptors antibodies or other macromolecules For enzyme inhibitor assay my classmate said that it is used to test the function of an enzyme by inhibiting it and see what goes wrong My doubt is that I have seen both terms enzyme inhibitor assay and enzyme inhibition assay during my web search and I am wondering if they are the same thing I saw in one paper that an enzyme inhibition assay was used to detect antibodies which is different from what my classmate said so I am confused My guess is that maybe the difference the answer our teacher is expecting is that the techniques used is different one centers on receptors while the other on inhibitors but really they re bind to each other but they can both be applied to something similar Would anybody mind sharing some ideas or shading light on this Reply with quote Robertsmith1 Robertsmith1 Posts 2 Joined Fri Oct 30 2015 8 56 am Fri Oct 30 2015 9 00 am Enzymatic phosphate exchanges are one of the overwhelming instruments for controlling the development separation and digestion system of cells The post translational alteration of proteins with phosphate prompts emotional changes in compliance bringing about the adjustment of tying catalysis and enlistment of effector particles that control cell flagging pathways Illustrations incorporate the enlistment of SH2 space containing proteins the actuation of quality
