That’s why we are one of the only providers to offer detailed processing data, technician notes, and even sample images before every batch shipment, ensuring you have full confidence in the quality and integrity of your samples. ### Matched Donor Whole Blood Procurement Available [Whole Blood Procurement](https://biosampleconnect.joined.bio/tissues) ### Quote Submission Form Start Here ## Request A Same-day Estimate Fill out the form to receive a proposal reflecting the approximate project pricing and timelines the same day as submission. Requests must be placed by 3pm EST, Monday - Friday. [Available Sample Types](https://biosampleconnect.joined.bio/biosample-procurement) Ask The Team ## Frequently Asked Questions Can buffers or stabilizing reagents be added to the sample prior to shipping? Certainly! Any safe reagent or buffer can be incorporated into any biofluid sample before shipping. Just inform your BSC representative during the project planning phase. Are first void urine samples available? The first urination of the day can be collected without any extra charge. How much CSF can be obtained per donor? Our affiliated clinics generally obtain between 0.5 and 2mL of CSF from each donor. Are donor matched tissues available? Certain conditions permit the gathering of donor-matched tissues. For instance, synovial membrane tissue can be obtained together with synovial fluid. Discuss with your BSC representative during study planning to assess feasibility. ## Resources [See more](https://biosampleconnect.joined.bio/resources) ### [Impact of Mergers in the Biospecimen Industry](https://biosampleconnect.joined.bio/resources/impact-of-mergers-in-the-biospecimen-industry) ### [Expanding Global Tissue Procurement Networks](https://biosampleconnect.joined.bio/resources/expanding-global-tissue-procurement-networks) ### [Whole Blood Processing into Serum/Plasma within 45 Minutes](https://biosampleconnect.joined.bio/resources/whole-blood-processing-into-serum/plasma-within-45-minutes) [![BSC-JB Stacked 400px](https://biosampleconnect.joined.bio/hs-fs/hubfs/BSC-JB%20Stacked%20400px.png?width=500&height=174&name=BSC-JB%20Stacked%20400px.png "BSC-JB Stacked 400px")](https://www.biosampleconnect.com) - [Resources](https://biosampleconnect.joined.bio/resources) - [Contact Us](https://biosampleconnect.joined.bio/contact-us) - [Purchase Terms](https://biosampleconnect.joined.bio/purchase-terms) - [Terms of Use](https://biosampleconnect.joined.bio/terms-conditions) - [Privacy Policy](https://biosampleconnect.joined.bio/privacy-policy) Joined Bio / BSC 450 Bedford Street Suite 2100 Lexington, MA 02420 United States ![Registered Scientist.com Supplier](https://biosampleconnect.joined.bio/hs-fs/hubfs/Registered%20Scientist.com%20Supplier.png?width=250&height=162&name=Registered%20Scientist.com%20Supplier.png "Registered Scientist.com Supplier") ![verified-supplier](https://biosampleconnect.joined.bio/hubfs/verified-supplier.svg "verified-supplier") ![5bb95c9342864-777246a749567d7b24e24ad5277b5590](https://biosampleconnect.joined.bio/hs-fs/hubfs/5bb95c9342864-777246a749567d7b24e24ad5277b5590.png?width=100&height=100&name=5bb95c9342864-777246a749567d7b24e24ad5277b5590.png "5bb95c9342864-777246a749567d7b24e24ad5277b5590") --- Copyright © 2025 Joined Bio, Inc.
