体外研究 |
3-CPs displays protective effect against UVB damage in all concentrations tested. About 50% inhibition of bacterial killing is observed when 12 ng of purified type 3 CPS is added to the OPKA. The addition of 30μL of mouse serum post-i.p. infection with WU2 (containing 0.4 to 0.7μg/mL released type 3 CPS) shows 26% to 52% inhibition of bacterial killing, comparable to what is observed when an equivalent amount of purified CPS is added |
推荐实验方法(仅供参考)

Kinase Assay |
To measure the inhibitory effect of releaseing type 3-CPs on bacteria killing, an OPKA is performed with the addition of culture supernatant or mouse serum obtained at 24 h following i.p. injection with 103 CFU of the S. pneumoniae WU2 strain. In each well, 10μL of diluted rabbit serum is mixed with 10μL of strain WU2 (1,000 CFU) and 10μL of culture supernatant or mouse serum for 30 min at room temperature before HL-60 cells and complement are added. The percent inhibition of bacterial killing is compared to that with the OPKA with the addition of ΔCPS WU2 culture supernatant or naive mouse serum containing no 3-CPs |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入 输出 )
