Lewis X trisaccharide-BSA (25 μg/mL; 30 min; before LPS stimulation of 10 ng/mL for 4 h) IL-12p40 and suppresses IL-12p70 protein expression induced by Lipopolysaccharide (LPS)[1].
Lewis X trisaccharide (2 μM; 30 min; before LPS stimulation of 10 ng/mL for 2 h) decreases nuclear NF-κB concentration in mice bone marrow derived dendritic cells (BDDCs)[1].
Lewis X trisaccharide-BSA (25 μg/mL; 48 h) or Lewis X trisaccharide (5 μg/mL; 48 h) plus ovalbumin (OVA, 25 μg/mL) increases cytokines (IL-4, IL-13, and INF-γ) level in mice splenocytes[1].
Lewis X trisaccharide-containing glycoconjugates stimulates B cells to proliferate and to produce factors that down-regulates the TH1 immune response and up-regulates the TH2 immune response[2].
Lewis X trisaccharide ( 5 μg, combinded with 50 μg ovalbumin; s.c.; once a week for 2 weeks) regulates IgE/TH2 responses, and selectively increases the IgE and IgG1 responses in C3H mice, independent of the LPS-TLR4 signaling[1].

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。
