Serum or Plasma is the best way to detect cytokines via ELISA? Most of the paper suggests to do ELISA from Serum. But in our lab we collect plasma. Is there any difference to be found while doing.. I have done ELISA test to determine the level of cytokine in blood. There are many studies suggesting that either plasma or serum can be used for the assay. I would like to discuss with all of you.. In this blog post we explain how to prepare plasma and serum samples for ELISA Kits. How to Prepare plasma and serum samples for ELISA Kits For plasma: Collect whole blood into an EDTA, Citrate or Sodium heparin tube (e.g. BD vacutainer, Cat # 8001302 or 16852). Centrifuge 10 minutes at 3,000 rpm; Aliquot into small tubes and store at -80°C until use. For serum

Serum is the liquid fraction of whole blood that is collected after the blood is allowed to clot. The clot is removed by centrifugation and the resulting supernatant, designated serum, is carefully removed using a Pasteur pipette. Plasma is produced when whole blood is collected in tubes that are treated with an anticoagulant. The blood does not clot in the plasma tube. The cells are removed by centrifugation. The supernatant, designated plasma is carefully removed from the cell pellet using.

Serum and Plasma are known for containing interference factors (hemolytic/bilirubin/lipemic/blood, etc) that may inhibit the assay's biological components (capture/detection antibodies), as well as potentially affect absorbance readings. To mitigate suspected interference factors: Dilution is the best way to mitigate interference factors What you could do is obtain matched serum and plasma samples either commercially or from individuals in the lab (5 sets for example) and assess the matched pairs in the assays unspiked and spiked with exogenous analyte. If you don't see huge differences between the plasma and serum, then you are probably OK Plasma. Collect whole blood into anti-coagulant containing tube, such as BD Vacutainer Coagulation tubes (Cat #: 363080/363080) or add 0.1 M sodium citrate to 1/10 final volume. Centrifuge at 3,000 rpm for 10 min at 4°C. Immediately aliquot supernatant (plasma) and store samples at -80°C. Minimize freeze/thaw cycles. Urin

Serum - Use a serum separator tube (SST) and allow samples to clot for 30 minutes at room temperature before centrifugation for 15 minutes at 1000 x g. Remove serum and assay immediately or aliquot and store samples at ≤ -20 °C. Plasma - Collect plasma using EDTA, heparin, or citrate as an anticoagulant. Centrifuge for 15 minutes at 1000 x g within 30 minutes of collection. Assay immediately or aliquot and store samples at ≤ -20 °C General Tips For ELISA Sample Preparation Serum, plasma, cell, and tissue extracts are typically diluted by 50% with binding buffer. The total protein concentration of homogenate should be at least 1 mg/mL. However, 2 mg/mL or more would be better Serum is the liquid fraction of whole blood that is collected after the blood is allowed to clot. The clot is removed by centrifugation and the resulting supernatant, designated serum, is carefully removed using a Pasteur pipette. Plasma is produced when whole blood is collected in tubes that are treated with an anticoagulant

There are a handfull of papers out trying to correlate the conc's of cytokines in serum to plasma and determine if one is better for ELISAs. Some say there is no difference and other say there is a large difference. My experience is that 95% of time, the researcher uses the method they are most comfortable with or that which their colleagues in their field use most often. And, unsurprisingly, that often works just fine This may account for one of the largest differences seen in the reported ELISA measurements of SP-D in serum/plasma, as the highest concentrations of SP-D came from the non-commercially available ELISA which used purified, native SP-D as a standard; this is opposed to almost all others, which used recombinantly expressed SP-D as a standard. Regardless of whether the antibodies used were raised against recombinant SP-D or purified native, because the post-translational. Following collection, plasma or serum should be cryopreserved at -80º C. Cytokines and chemokine levels can be measured by Enzyme-linked immunosorbent assay (ELISA). However, this method is time consuming and allows measurement of only one factor at a time

The samples available to ELISA detection usually have various types, such as serum, plasma, urine, and cell culture supernatant or tissue homogenate. The pretreatment methods for different types of samples are also different. Appropriate sample treatment is the first step to ensure the correctness and accuracy of ELISA detection. Here we'll introduce treatment methods for different sample.

Two of them is plasma and serum. These two terms are used frequently but play different roles in the body. Serum and plasma are the liquid part of the blood. These components remain when the cells' components are taken out. Serum is the liquid component of the blood that remains once the blood has clotted. On the other hand, plasma is the liquid part that remains when clotting does not take place and the anticoagulant is added Sera and plasma were frozen and stored at −70°C until HSV-2 antibody testing was performed.
