Whole Blood Sample Collection in Proteomics Analysis

In proteomics detection, the collection of whole blood samples is an important step: it is done through venipuncture, ensuring the use of aseptic techniques to avoid contamination. The collected blood should be immediately labeled and refrigerated to maintain the integrity of the sample and reduce protein degradation. In addition, the samples should be transported and stored under low temperature conditions until proteomics analysis is performed. The general steps are as follows.

 

Preparation

Before collecting blood samples, you should ensure that all necessary materials (such as sterile blood collection tubes, needles, alcohol cotton pads, etc.) are ready. You can use aseptic operation to prevent sample contamination.

 

Select Blood Collection Site

Common blood collection sites include the veins in the forearm. Disinfect the blood collection site with alcohol cotton before blood collection to reduce the risk of infection.

 

Blood Collection

Please use an appropriately sized needle to gently insert it into the selected vein to avoid venous bruising or injury. The blood flows into the blood collection tube through the needle.

 

Sample Processing

You can appropriately process the whole blood sample according to  the required proteomics analysis method. For example, if plasma proteome analysis is needed, separation of plasma through steps like centrifugation is necessary.

 

Sample Storage

Store the collected blood samples under appropriate conditions, such as low temperature environment to avoid protein degradation.

 

In proteomics analysis, whole blood samples can provide a wide range of biological information about an individual, which is crucial for the diagnosis and therapeutic research of diseases. However, special attention is needed when collecting and processing whole blood samples to ensure the quality and safety of the samples.
