ODN 1668, a class B CpG ODN (oligodeoxynucleotide), is a TLR-9 agonist. ODN 1668 is an immunostimulatory sequence and can be used as vaccine adjuvant. Sequence: 5'-tccatgacgttcctgatgct-3'[1][2].
ODN 1668 induces TNF-α secretion and promotes polyclonal B cell activation[1].
ODN 1668 (10 nmol) stimulates responses to protein antigen[1].
ODN 1668 (1 or 5 mg/kg; i.p. or s.c.; once) causes moderate fever and anorexia in rats[2].
| Animal Model: | C57BW6 mice[1] |
| Dosage: | 10 nmol |
| Administration: | 300 μg OVA (ovalbumin) in PBS or liposomes containing OVA were injected with or without 10nmol ODN in the hind footpads of C57BW6 mice. A boost of the sameinoculum was given at 2 weeks, and 1 week later blood was taken for serum antibody titering. |
| Result: | Strongly potentiated the antibody response and induced class switching toward IgG2a and IgG2b. Showed B cell blast formation and a more than twofold increase in B7.2 (CD86) and IL-2 receptor-α (CD25) surface expression. |
| Animal Model: | Male Wistar rats with body weights in the range of 175-200 g[2] |
| Dosage: | 1 mg/kg or 5 mg/kg |
| Administration: | Intraperitoneal and subcutaneous injection, once |
| Result: | Caused moderate fever and anorexia. Induced a significant increase of IL-6. Increased expression of inflammatory genes and activated inflammatory transcription factors. |

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
