1. Why use Human AB Serum, Converted from Octaplas®, Pooled Plasma (Human), Xeno-Free, Virus Inactivated (viHABS) Closed System Solutions (CSS)?
Human AB Serum is used as a media supplement in cell culture. This product is considered a comparable alternative to fetal bovine serum or other animal-based products. Raw material donor selection ensures that the product is devoid of antibodies for A and B blood antigens, therefore minimizing immune reactivity in cell culture. We leverage Octaplas® (pharmaceutically licensed virus inactivated and prion-ligand treated plasma) as the raw material, offering greater batch-to-batch consistency and a unique safety profile.
Akron’s novel viHABS CSS formulation and sterile bag packaging are ideal for closed-system commercial cell therapy manufacturing, allowing for the introduction of supplement material into culture media in a fully contained manner.
2. What are the recommended storage conditions for viHABS CSS?
We recommend storing this product at -20 °C. If serum content is not being used all at once, we suggest aliquoting into the desired volume and storing at -20 °C until needed. Avoid repeated freeze-thaw cycles.
3. What are the shipping conditions for viHABS CSS?
This product ships with dry ice.
4. What is the shelf-life for Human AB Serum, Converted from Octaplas®, XF, VI, CSS?
This product is currently under a formal stability program to determine shelf life.
5. What is the thawing procedure for viHABS CSS?
Thaw at 2-8 °C for 24 hours, then allow to reach room temperature. If further warming is required, use a controlled 37 °C environment to bring up to temperature. Avoid multiple freeze-thaw cycles, prolonged exposure to 37 °C, and temperatures above 37 °C.
6. Do particulates ever form after thawing?
Precipitates will form in certain units of serum during the thawing process. This is normal and common behavior for serum products and it will not negatively affect cell culture. These precipitates do not negatively impact the safety or quality of the material. This product is sterile filtered before filling and every lot is tested for mycoplasma and sterility per USP.
7. Should I heat inactivate the Human AB Serum before use?
Our Human AB Serum product is sold ready to use directly as a supplement to your culture medium, but we have seen increased performance with certain cell lines after a heat treatment process is applied to the product before use. If performing this, we recommend a temperature of about 56 °C for 30 minutes; inactivation for a longer time may have a negative effect on cell growth due to denaturing of proteins and growth factors.
8. Where is the raw material sourced?
viHABS CSS is converted from Octaplas®. Only plasma from US donors (frozen within 8 hours of collection) is used to manufacture Octaplas® and ultimately the Human AB Serum. For Octaplas®, individual donor identification, registration, and education takes place in FDA-licensed centers which comply to the requirements for the collection of source plasma as specified in “The Collection, Fractionation, Quality Control, and uses of Blood and Blood Products,“ published by the WHO Technical Report Series 840. This allows for traceability down to the single donation unit, if needed.
9. How are the raw material donations screened?
There is a deferral check and questionnaire at each donation, as well as a physical assessment, per 21 CFR 630.10. Each plasma unit used as raw material is virus tested per 21 CFR 610.40 at the time of collection and found negative or non-reactive for Hepatitis B surface Antigen (HBsAg), antibodies to Human Immunodeficiency Virus (HIV)-1/2 (anti-HIV-1/2) and antibodies to Hepatitis C Virus (anti-HCV). HBV and HIV-1/2 serological tests are also performed on each plasma pool. Nucleic Acid Testing (NAT) is also performed at different manufacturing stages for HIV, B19V, HAV, HBV, HCV and HEV.
10. What process is used for viral inactivation?
Viral inactivation of enveloped viruses is accomplished via solvent detergent (S/D) treatment (see Technical Overview).
11. What are the advantages of S/D treatment versus other inactivation methods currently used?
S/D treatment has long been a standard and robust virus inactivation process for plasma products. S/D and pH inactivation are generally effective against enveloped viruses. Heat inactivation, irradiation, chromatography and filtration methods have been shown to have some effect on non-enveloped viruses, as well as enveloped viruses. The viral safety for plasma products should be validated with a panel of characterized viruses, and pathogen safety studies should be incorporated for all relevant steps of the manufacturing process. A combination of these methods are used to reduce the overall risk of adventitious viruses and bloodborne pathogens in plasma products.
12. Are non-enveloped viruses inactivated also?
S/D treatment is not effective against non-enveloped viruses. However, the presence of standardized levels of neutralizing antibodies in the Octaplas® plasma pool along with virus load control by NAT screening minimizes the risk of transmitting non-enveloped viruses such as HAV, and parvovirus B19V (see Technical Overview).
13. Is there S/D agent remaining in the plasma that might affect cell growth?
In the Octaplas® manufacturing process, the S/D reagents are removed by sequential oil and solid phase extraction procedures. Final levels of residual S/D agents in Octaplas® are below FDA-specified limits for product release. These remaining levels of S/D agents are below what has been found to impair cell growth.
14. What is the difference between plasma and serum?
Whole blood is composed of plasma, red and white blood cells, and platelets. Plasma is the part of blood that carries nutrients, antibodies and hormones throughout the body. It contains serum and clotting factors. Serum is plasma without clotting factors.
15. Which cell types are suitable?
Akron’s Human AB Serum, Converted from Octaplas®, XF, VI can be used as a replacement in any cell culture protocols that currently use human AB serum or fetal bovine serum (FBS). Optimization may be required.
16. Is the performance comparable to competitor products / FBS?
Cell proliferation and viability are comparable to other serum products on the market, including FBS, while offering increased safety associated with the raw materials and manufacturing process (ask us for supporting data).
17. Do you have an SDS for this product?
Yes, an SDS is available upon request.
18. Is this an injectable-grade or clinical-grade material?
No, this product is not for direct use in humans. See intended use below.
19. What is the intended use for the product?
For research use or further manufacturing use in ex vivo cell therapy applications. This product is not intended for direct in vivo use or for direct clinical use as a drug, therapeutic, biologic, or medical device.
20. What packaging options are available?
Akron’s AB Serum CSS comes packaged in a sterile bag chamber made from Ethylene-vinyl acetate (EVA) for inert bioreactivity and increased flexibility. The 6” outlet tubing on the distal end of the Y connector is made from weldable polyvinyl chloride (PVC) (2.5 mm ID x 4.1 mm OD). This product can be customized, with different packaging materials and/or fill volumes available under contract.
21. What closed connection options are available to remove the material from the bag?
It is recommended to weld directly to the 6” PVC outlet tubing. A direct connection via a female Luer lock connector is available on the outlet tube. There are also two twist-off spike ports for entry with a spike adapter if desired (for full instructions, see “Methods of Use” document).
