About our Donors
Chronic lymphocytic leukemia (CLL) is a hematologic cancer and the most common type of leukemia. The cause is the uncontrolled growth of B cells that accumulate in the blood, bone marrow, and lymphoid tissues, which crowd out healthy blood cells, including red blood cells and non-B cell white blood cells. This leads to lymphocytosis (elevation of white blood cell levels, specifically of B cells) , enlarged lymphoid tissues, and thrombocytopenia (the loss of red blood cells).
Our CLL donors are sourced from a renowned world-class blood collection center that has been a pioneer in many screening processes. All donors have been tested for various infectious diseases, including HIV and Hepatitis B/C, as well as normal levels of hemoglobin. Further, donors undergo a screening questionnaire to disclose vital statistics, medication, cancer history, and travel history to ensure that they are healthy and their PBMCs will reliably serve your research endeavors.
Application Summary for Human CLL PBMCs
PBMCs from CLL patients are predominantly used to identify and characterize various cell populations in the peripheral blood of these individuals. Researchers often use flow cytometry to identify surface proteins and categorize different cell types. In addition, certain cell populations are purified to identify intracellular proteins by western blot analysis and/or for functional characterization. Other uses include acting as targets to test the efficacy of biologics.
Isolation of PBMCs
Once the blood is received at our lab from the local collection center, PBMCs are isolated by performing density centrifugation with Ficoll, a high molecular weight sucrose solution, to remove red blood cells under sterile conditions. Depending on the species (human or non-human) of blood, either 1.077 or 1.084 g/ml Ficoll is used, resulting in a perfect layer of mononuclear cells that are separated from plasma, platelets, granulocytes, and erythrocytes. Additional quality control steps are taken to isolate and prepare PBMCs that ensure the highest viability for cryopreservation and downstream experimental applications.
Cryopreservation and Storage
Our human PBMCs are cryopreserved carefully using iQ Biosciences’ cryopreservation protocol that ensures high viability (> 90%) after thawing.
Cells should be stored at < -120°C once they are received, such as within a liquid nitrogen tank (vapor phase).
Quality Control Process
We implement random sampling per lot to test for viability and cell counts to ensure they meet specifications, which are recorded on the Certificate of Analysis that is included with each shipment. Cell counts are obtained using a manual hemocytometer and then cross-referenced with an automated cell counter. Each lot is also characterized for unique cell populations by immunophenotyping, in which the results are also recorded on the Certificate of Analysis.
We are happy to accommodate the following donor requests if inventory is available. Feel free to inquire prior to ordering, or specify your request in the "Order notes" section during the checkout process:
- Single or multiple donors for a particular product (SKU). Indicate the number of vials from each individual donor
- Positive or negative for EBV or CMV (for healthy donors only)
- Good responder or non-responder to tetanus antibody (for healthy donors only)
- HLA types for Class I and Class II alleles (for healthy donors only)
- Donor(s) with a higher percentage of the cells of interest (e.g., B cells, CD4+ cells, CD8+ cells, NK cells, etc.)
- Gender, age, body mass index (BMI), or ethnicity
We are Committed to Ethical Practices
iQ Biosciences’ human primary cell products are lawfully obtained in accordance with Local, State, and Federal U.S. requirements, and the collection of cells complies with ethical requirements. Our cells are obtained from normal or disease patient volunteers participating in a donor program that is approved by an Institutional Review Board (IRB) or Human Subject Committee. A signed and witnessed consent form is obtained from donor volunteers prior to starting the collection protocol. Strict controls on personal identifiers of volunteers are in place in order to protect their privacy.
For US customers, we ship via FedEx Overnight Shipping. Shipping charges will vary per shipping address (based on ZIP code) and are estimated to be $110.
For international (non-US) customers, we work closely with you and our couriers to ensure all necessary documentation is in place for international shipments to significantly reduce the chance of delays at Customs. For the export of non-human primate samples, this includes preparing CITES permits, as well as any other documentation as required by country. Please submit an inquiry to firstname.lastname@example.org for your estimated time of delivery and shipping charges.
