Karl Landsteiner famous quotes

On the whole, at least in the author's experience, the preparation of species-specific antiserum fractions and the differentiation of closely related species with precipitin sera for serum proteins does not succeed so regularly as with agglutinins and lysins for blood cells. This may be due to the fact that in the evolutional scale the proteins undergo continuous variations whereas cell antigens are subject to sudden changes not linked by intermediary stages.

The morphological characteristics of plant and animal species form the chief subject of the descriptive natural sciences and are the criteria for their classification. But not until recently has it been recognized that in living organisms, as in the realm of crystals, chemical differences parallel the variation in structure.

Owing to the difficulty of dealing with substances of high molecular weight we are still a long way from having determined the chemical characteristics and the constitution of proteins, which are regarded as the principal con-stituents of living organisms.

A single kind of red cell is supposed to have an enormous number of different substances on it, and in the same way there are substances in the serum to react with many different animal cells. In addition, the substances which match each kind of cell are different in each kind of serum. The number of hypothetical different substances postulated makes this conception so uneconomical that the question must be asked whether it is the only one possible. ... We ourselves hold that another, simpler, explanation is possible.

I have recently observed and stated that the serum of normal people is capable of clumping the red cells of other healthy individuals... As commonly expressed, it can be said that in these cases at least two different kinds of agglutinins exist, one kind in A, the other in B, both together in C. The cells are naturally insensitive to the agglutinins in their own serum.

Narration is as much a part of human nature as breath and the circulation of the blood.

Dear friends, have you begun to sing the "new song? " Loved ones are singing it in the heavenly home, and we may sing it here; and by and by we shall join them, gaze with them on the risen, glorified Lord, and our voices will mingle in the "new song" "unto Him that loved us, and washed us from our sins in His own blood, to Him be glory and dominion for ever and ever.

Never forget that the most sacred right on this earth is mans right to have the earth to till with his own hands, the most sacred sacrifice the blood that a man sheds for this earth.

If we consider how greatly he has sinned against the masses in the course of the centuries, how he has squeezed and sucked the blood again and again; if furthermore, we consider how the people gradually learned to hate him for this, and ended up by regarding his existence as nothing but punishment of Heaven for the other peoples, we can understand how hard this shift must be for the Jew.

You should employ your little grey cells

For over two billion years, through the apparent fancy of her endless differentiations and metamorphosis the Cell, as regards its basic physiological mechanisms, has remained one and the same. It is life itself, and our true and distant ancestor.

Looking back 25 years later, what I may say is that the facts have been far better than the dreams. In the long course of cell life on this earth it remained, for our age for our generation, to receive the full ownership of our inheritance.

What we have done in the past is not sufficient now to prepare our youth.

Food is so important - it sustains us, it provides a social focal point, and it is fun. I cannot unravel the difference between love in my family and the preparation of food because they are so closely woven.

NECTAR, n. A drink served at banquets of the Olympian deities. The secret of its preparation is lost, but the modern Kentuckians believe that they come pretty near to a knowledge of its chief ingredient.
