兔Toll样受体4(TLR4)ELISA试剂盒
Rabbit Toll-like receptor 4(TLR4)ELISA Kit
本试剂盒用于测定兔血清，细胞上清及相关液体样本中Toll 样受体4(TLR4)的含量。
This kit allows for the determination of TLR4 concentrations in Rabbit serum, cell culture
supernatant, and other biological fluids.
兔Toll样受体4(TLR4)ELISA试剂盒样本处理方法：
1. 血清：室温血液自然凝固10-20 分钟，离心20 分钟左右（2000-3000 转/分）。仔细收集上
清，保存过程中如出现沉淀，应再次离心。
2. 血浆：应根据标本的要求选择EDTA 或柠檬酸钠作为抗凝剂，混合10-20 分钟后，离心
20 分钟左右（2000-3000 转/分）。仔细收集上清，保存过程中如有沉淀形成，应该再次
离心。
3. 尿液：用无菌管收集，离心20 分钟左右（2000-3000 转/分）。仔细收集上清，保存过程
中如有沉淀形成，应再次离心。胸腹水、脑脊液参照实行。
4. 细胞培养上清：检测分泌性的成份时，用无菌管收集。离心20 分钟左右（2000-3000 转/
分）。仔细收集上清。检测细胞内的成份时，用PBS（PH7.2-7.4）稀释细胞悬液，细胞
浓度达到100 万/ml 左右。通过反复冻融，以使细胞破坏并放出细胞内成份。离心20 分
钟左右（2000-3000 转/分）。仔细收集上清。保存过程中如有沉淀形成，应再次离心。
5. 组织标本：切割标本后，称取重量。加入一定量的PBS，PH7.4。用液氮迅速冷冻保存备
用。标本融化后仍然保持2-8℃的温度。加入一定量的PBS（PH7.4），用手工或匀浆器
将标本匀浆充分。离心20 分钟左右（2000-3000 转/分）。仔细收集上清。分装后一份待
检测，其余冷冻备用。
6. 标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上
进行试验，可将标本放于-20℃保存，但应避免反复冻融，不能检测含NaN3 的样品，因NaN3 抑制辣根过氧化物酶的（HRP）活性。
Specimen requirements
1. serum- coagulation at room temperature 10-20 mins，centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
2. plasma-use suited EDTA or citrate plasma as an anticoagulant,mix 10-20 mins ,centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If
precipitation appeared, Centrifugal again.
3. Urine-collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m.remove supernatant, If precipitation appeared, Centrifugal again. The Operation of Hydrothorax and cerebrospinal fluid Reference to it.
4. cell culture supernatant-detect secretory components, collect sue a sterile container,centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant,detect the composition of cells, Dilut cell suspension with PBS （ PH7.2-7.4 ） , Cell concentration reached 1 million / ml, repeated freeze-thaw cycles, damage cells and release of intracellular components, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
5. Tissue samples- After cutting samples, check the weight,add PBS（PH7.2-7.4）, Rapidly frozen with liquid nitrogen, maintain samples at 2-8℃ after melting,add PBS（PH7.4）,Homogenized by hand or Grinders, centrifugation 20-min at the speed of 2000-3000 r.p.m.remove supernatant.
6. extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t,specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles.Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
