Human-derived serum faces challenges regarding biosafety, regulatory compliance, and availability. To address these issues, AccuSift utilizes "organoid technology" to simulate the human in vitroenvironment, producing an artificial serum that can replace human serum or other animal serum matrices.

AccuSift Artificial Serum Matrix:

• Function: A compliant and safe alternative to human serum.

• Advantages: Produced using "organoid technology," featuring low matrix effects, minimal inter-batch variation, zero risk of biological contamination (free from endogenous human/animal pathogens), excellent stability, lyophilization-compatible, and fully compliant with regulations.

• Disadvantages: Cannot 100% replicate the full complexity of all components found in human serum; higher production cost.

  
  

Comparison:

Human Serum:

• Function: Considered the "gold standard" matrix for calibrators and quality control materials.

• Advantages: No matrix effect; most accurately simulates real patient samples.

• Disadvantages: Biosafety risks (HIV/HBV, etc.), restricted by regulations (prohibition of trade), high lot-to-lot variability, ethical concerns, and difficult procurement.

Other Brands' Artificial Serum:

• Function: Also serves as a substitute for human serum, used for protein stabilization, blocking agents, etc.

• Advantages: Cost-effective, scalable for mass production, relatively defined composition (e.g., formulated with recombinant albumin), smaller inter-batch variation.

• Disadvantages: If formulated simply with buffers and recombinant proteins, it may exhibit high matrix effects, failing to fully simulate the complex interactive environment of human serum, potentially causing interference in sensitive assays.

Animal Serum (e.g., Bovine, Equine, Ovine):

• Function: Commonly used as a blocking agent, cell culture supplement, or matrix for low-end quality control products.

• Advantages: Widely available, low cost, easy to procure, relatively high biosafety (does not transmit human diseases).

• Disadvantages: Significant matrix effects (vastly different from target human samples), contains animal-derived antibodies or hormones that may interfere with detection, high lot-to-lot variability, and may contain interfering substances like endogenous biotin.

  
  

Applications: Can be used as a matrix for standards, quality control materials (QCs), reference materials, diluents, calibrators, and as a negative control.

Note: Not intended for cell culture or clinical experimentation.
