Application
脂多糖（LPS）是革兰氏阴性细菌细胞壁的特征组分。LPS及其脂质A部分通过Toll样受体4（TLR4）刺激先天免疫系统的细胞，Toll样受体 4是Toll样受体蛋白家族的成员，其识别常见的病原体相关分子模式（PAMP）。
Biochem/physiol Actions
脂多糖 (LPS) 位于膜的外层，并且在非包封的菌株中，其暴露于细胞表面。它们有助于外膜的完整性，并可保护细胞免受胆汁盐和亲脂性抗生素的作用。
General description
本品为从鼠伤寒沙门氏菌中提取的 TCA。来源菌株为 ATCC 7823。该 LPS 血清型已被用于诱导大鼠和豚鼠的 NOS。
Preparation Note
该产品可溶于水（5mg / ml）或细胞培养基（1mg / ml），产生浑浊的淡黄色溶液。当涡旋并升温至70-80 oC后，在盐水中可获得更高浓度的溶液（20mg/ml），但仍然是浑浊的溶液。脂多糖是一种在各种溶剂中都形成胶束的分子。在水和磷酸盐缓冲盐水中可观察到浑浊的溶液。有机溶剂无法使溶液变澄清。甲醇会产生含有漂浮物的混浊悬浮液，而水会产生均匀的混浊溶液。

Exposure to heat stress suppresses poultry immune responses, which can increase susceptibility to infectious diseases and, thereby, intensify the negative effects of heat on poultry welfare and performance. Identifying genes and pathways that are affected by high temperatures, especially heat-induced

Thymus is the crucial site for T cell development and once believed to be immune privileged. Recently, thymus has gained special attention as it is commonly targeted by infectious agents which may cause pathogenic tolerance and subsequent immunosuppression. We analyzed

Exposure to high temperatures is known to impair immune functions and disease resistance of poultry. Characterizing changes in the transcriptome can help identify mechanisms by which immune tissues, such as the thymus, respond to heat stress. In this study, 22-day-old
