Buying Guide: Purchasing Biospecimens for Research


In biomedical research, reagents, chemicals and biologicmaterial are crucial and in the past, researchers had to procure biospecimens through unreliable and, in some cases, unethical means. However, with the advent of research ethics, the procurement of biospecimens has become a central aspect of human subjects protection and legal compliance. To fully understand how to go about buying biospecimens, it’s important to first know what ethical regulations and quality standards should be met by the supplier.

What are Biospecimens?

Any biological samples that are collected from living organisms, ranging from humans and animal tissue to bodily fluids, and blood or urine are what are generally called biospecimens. This material is essential for biomedical research, specifically for evaluating the interaction of various chemicals and compounds with various states of tissue. Biospecimens help researchers better understand the cellular, molecular and genetic nature of living organisms. Through their research, it is possible to develop treatments and diagnostics for different diseases affecting living organisms, especially human beings.

Importance of Obtaining Right Quality of Biospecimens

It is important to get access to the highest quality of biospecimens to obtain accurate and credible experimental results. There are basic quality criteria that assure researchers of stability and consistency in results. One way of ascertaining quality of biospecimens is by evaluating how they are collected and stored. Companies dealing in biospecimens can reduce contamination and degradation of the biospecimens by increasing the quality their collection and storage systems in accordance with industry standards.

Apart from collecting and storing, the biospecimens must be properly labeled to ensure they are easily identified and tracked as they move from one area of a lab to the next. The companies dealing in biospecimens should always ensure they have the best storage systems comprising of cryogenic, frozen and refrigerated areas.

Selecting The Right Vendors For Your Biospecimens

In order to ensure you have durable and reliable samples, and then the first step is to identify the best vendor to purchase biospecimens from. You can tell a reputable vendor by how much experience and expertise they have in handling biospecimens. Sometimes, mistakes do occur and a reliable biospecimen vendor will ensure they deal with risks of contamination before they can process another order. However, here are a few more factors you can consider when searching for a biospecimen vendor.

  1. Experience: A vendor with a strong track record of providing high-quality biospecimens is more likely to meet the needs of researchers. Look for a vendor with a proven history of providing reliable, high-quality samples.
  1. Customer Service: A vendor with a commitment to customer service is more likely to provide the support and assistance needed to ensure the success of a research project. Look for a vendor that is responsive and willing to work with researchers to meet their needs.
  1. Quality Control Processes: A reputable vendor will have established quality control processes in place to ensure the reliability and consistency of their biospecimens. This includes processes for collecting, storing, and distributing samples, as well as processes for verifying the quality of the samples.
  1. Source of Samples: The origin of the biospecimens can impact their quality and reliability. A reputable vendor should be transparent about the source of their samples and should be able to provide information about the individuals from whom the samples were collected.
  1. Compliance with Regulations: Biospecimens are subject to a number of regulations, including ethical, legal, and regulatory requirements. A reputable vendor should be able to demonstrate compliance with these requirements.

Factors Affecting Cost of Biospecimens

Cost of biospecimens is a crucial factor affecting their availability. Sometimes, international and domestic supply chains can shut down affecting availability and this increases demand. Therefore, biospecimens are also susceptible to the same risk factors affecting other products and services. However, the most common factors affecting the cost of biospecimens are:

Type of Biospecimen

The type of biospecimen you require will affect he cost, since some types of tissue or fluid samples are difficult to procure in bulk. For example, blood is more expensive compared to urine due to differences in cost of collection and processing.

Quantity and Quality

The more the quantity of biospecimens you need, the higher the cost. This largely results from costs relating to collection, packaging and even storage. Similarly, high quality biospecimen fetch higher costs, and though quality is subjective, it largely relies on the needs of the researcher and what’s available on the market. Well preserved biospecimens tend to have better quality than others.

Determine the specific needs of the research project: This includes identifying the type of biospecimen required, the quantity needed, and the desired level of quality. This information can help to determine the cost of the biospecimens and guide budgeting decisions.

Tips to Reduce Overall Cost of Biospecimen

You can always find strategies to reduce your costs of procuring biospecimen. Though this is an ethically ambiguous area, it is always important to consult the legal provisions on procurement and access to biospecimen. One way of reducing your overall costs is by negotiating directly with the vendors. Most vendors are willing to vary the costs of their biospecimen to cater to buyers who are either buying in bulk or require specialized and rare biospecimens, which would otherwise lack mass market.

Another important tip that most biospecimen researchers opt for is to buy from alternative sources. The market for trade in biospecimens is highly regulated, but there are loopholes that allow researchers to gain access of certain biospecimen away from the traditional markets. For example, finding blood samples don’t require a highly regulated environment; you can simply ask for volunteers to come and donate at your facilities.

In conclusion, as scientific research in the fields of immunology and cell therapies grows, availability of biospecimens will become more critical. Most research companies have entered into partnerships with biospecimen firms and this allows them priority access to any kind of biospecimen they need at a pre-arranged cost. This trend is likely to continue and it will affect budget and costing plans of any research team looking for biospecimens.
