Discussion Overview

The discussion revolves around the mixing of frozen blood plasma with fresh red blood cells for the purpose of studying the optics of whole blood, specifically using Raman spectroscopy and chemometric methods. Participants explore the biochemical implications of such mixing and the necessary conditions to maintain the integrity of the samples.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant questions whether mixing 40% fresh red blood cells with frozen plasma would harm the biochemistry of the samples.
  • Another participant notes that obtaining plasma involves removing more than just red blood cells and mentions the need for anticoagulants to prevent coagulation in whole blood.
  • There is a concern raised about whether allowing blood cells to settle at the bottom of the vial would alter the proteins in the plasma.
  • A participant seeks clarification on the purpose of studying the optics of whole blood and the methods being employed, indicating a need for more context.
  • One participant explains their intent to use Raman spectroscopy for a quantitative investigation of a protein, emphasizing the importance of maintaining turbidity in the plasma sample to mimic whole blood.
  • Participants express a lack of chemical or biological experience, highlighting a reliance on physics in their approach.

Areas of Agreement / Disagreement

There is no consensus on the biochemical effects of mixing plasma with red blood cells, and multiple viewpoints regarding the necessary conditions for maintaining sample integrity are presented. The discussion remains unresolved on the implications of these actions.

Contextual Notes

Participants acknowledge the complexity of blood composition and the potential need for anticoagulants, but there are uncertainties regarding the specific biochemical changes that may occur from the proposed mixing process.

Hello
I have some 40 doses of frozen blood plasma from different people, I have to study the optics of wholeblood. Is it possible to just mix it with (lets say 40%) of fresh red blood cells. Will this do any harm the the biochemistry?

In that case
What if I'll do it by my self? just letting the blood cells fall to the bottom of the vial at separate it. Will this change ex. proteins in the plasma?

I don't know what it might do to optics, but in order to obtain plasma, more than just the red cells are removed. But, also, the blood is treated with additives when it is separated to prevent other parts of the plasma matrix from forming clots with the red cells (if the blood is allowed to clot, then what's left is serum, not plasma).

Though, you'd probably have to add some sort of anticoagulant to work with whole blood too, otherwise it'll start coagulating in the vial within minutes.

I know that blood contains more than just plasma and red bloodcells., but only need to mix red blood cells and plasma. does this work with a anticoalating substrat or is the blood doing seveere chemistry when its done

Can you provide more detail on "study the opitcs of whole blood"? To what end? What information are you trying to extract? What method are you using?

well i am doing Raman spectroscopy and chemometric in a quantitative investigation of a protein. We will try to do it non invasive, but first we will build a model for quantification in whole blood. therefor its critical that my plasma sample has some turbidity like whole blood. We have very little chemical og biological experience ;) only physics
