 หัวเรื่อง:การเพาะเซลล์ BHK21C13 แบบซัสเปนชั่นด้วยน้ำยาเลี้ยงเซลล์ที่มีซีรั่ม 5๔ เพื่อการผลิตไวรัสและวัคซีนโรคปากและเท้าเปื่อย ผู้เขียน:Payont Sinsuwonkwat, Cherngchai Chumtarusmi สื่อสิ่งพิมพ์:pdf AbstractThese experiments were to decrease the amount of PEG treated serum (Bovine serum collecting from slaughter house and treated with 8% PEG 6000) in the medium without changing the character of cultured cells in order to produce high yield of FMD virus and good quality of FMD vaccine. The BHK21C13 suspension cell cultured in the medium containing 5% poly ethylene glycol (PEG) treated serum for 3 days at 37oC. pH 7.2 The cells were subcultured in the same medium and condition until the 7th passage. The 7th passage cells were inoculated by type 0 cattle 0 (OBKK/S1) FMD virus by cell sedimentation method. The inoculated cells were culture in the medium containing 1% PEG treated serum at 37oC. pH 7.4 and harvested at 18 hours for preparing the vaccines. The results showed that the BHK21C13 suspension cells could grow in the medium containing 5% PEG treated serum, and could produce high yield of FMD virus and good quality of FMD vaccine. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Preparation of Cellulose Acetate Membranes for Ultra- Nano- Filtrations) ผู้เขียน:Darunee Bhongsuwan, Tripob Bhongsuwan สื่อสิ่งพิมพ์:pdf AbstractCellulose acetate (CA) membranes were prepared from CA powder, formamide and acetone by phase inversion. Production conditions used included evaporation times of 20, 30 and 60 seconds, gelation temperature of 1 – 2 ?C and annealing temperature of 70 and 75?C. The product membranes were coded CA620-70, CA630-70 CA660-70, CA620-75, CA630-75 and CA660-75 and were tested to have Molecular weight cutoff (MWCO) between 1500 and 10000 Da. The pure water flux tests classified the membranes CA620-70, CA630-70 CA660-70, CA620-75 as ultra-filtration type and CA630-75 and CA660-75 as nano-filtration membranes. Tannin was easily filtered with the rejection of 78 - 100 % for different membrane types and pressures. Rejection of protein BSA was successful at nearly 100 % rejection for all the product membranes. SEM micrographs showed an average pore longest axis of 0.066 ? 0.029 micron and pore densities of 1.95 – 3.02 pores/micron2. The membrane strength was tested to have the ultimate tensile strength of 1.64 – 2.82 N, Young’s modulus of 54.74 – 175.36 MPa and the percent elongation at failure of 15.57 – 23.00 |
