Details
Description:Mouse monoclonal antibody to human serum amyloid A (SAA)
Purification:Protein G affinity purified
Product Type:Primary antibody
Target Protein:Human SAA
Immunogen:Highly purified recombinant human SAA (MW: 12 kDa)
Fusion Myeloma:Sp2/0-Ag14
Specificity:This monoclonal antibody reacts with natural and recombinant human SAA.
Species Reacitvity: Human, others not tested
Cross-Reactivity: Does not show any cross-reaction with other human cytokines or growth factors tested such as IL-1β, IL-8, MCAF, TGF-β and EGF.
Host / Isotype: Mouse, IgG2b Kappa
Formulation:Lyophilized from a solution in 0.01M PBS, pH 7.2
Reconstitution:Double distilled water is recommended to reconstitute the antibody.
Storage: Store at -20oC
Research Area:Acute phase protein. Inflammatory reaction.
Background:
SAA is an acute phase protein and a sensitive inflammatory marker. Cytokines such as IL-1, IL-6 and TNF-alpha stimulates hepatocytes to produce and release SAA. In acute phase, SAA in blood can increase to more than 1,000 folds of normal level. Prolonged and repeated elevation of SAA results in abnormal deposition of amyloid proteins in organ or tissue in insoluble beta pleated form. Determination of SAA levels is important for assessment of renal allograft rejection, estimation of tissue damage caused by myocardial infarction and severe angina, and diagnosis of inflammation in cystic fibrosis patients and in patients infected with virus.
Application:
ELISA:React with human SAA.
Western Blot: The antibody, when used at concentration of 0.1-0.5 μg/mL will allow visualization of 100ng/lane of recombinant human SAA.

所以一个细菌或病毒可以有很多的抗原。
荚膜是某些细菌在细胞壁外包围的一层粘液性物质，一般由糖和多肽组成，是细菌的一种特殊结构。
作用：
①抗吞噬作用：荚膜因其亲水性及其空间占位、屏障作用，可有效抵抗寄主吞噬细胞的吞噬作用。
②黏附作用：荚膜多糖可使细菌彼此间粘连，也可黏附于组织细胞或无生命物体表面，是引起感染的重要因素，具有荚膜的S-型肺炎链球菌毒力强，有助于肺炎链球菌侵染人体；废水生物处理中的细菌荚膜有生物吸附作用，将废水中的有机物、无机物及胶体吸附在细菌体表面上。
③抗有害物质的损伤作用：处于细菌细胞最外层，荚膜犹如盔甲可有效保护菌体免受或少受多种杀菌、抑菌物质的损伤，如溶菌酶、补体等。
④抗干燥作用：荚膜多糖为高度水合分子，含水量在95%以上，可帮助细菌抵抗干燥对生存的威胁。
⑤当缺乏营养时，荚膜可被利用作碳源和能源，有的荚膜还可作氮源。
颗粒型抗原,除了有细菌、红细胞、螺旋体等天然颗粒型抗原,还有吸附有可溶性抗原的非免疫相关颗粒.
颗粒性抗原光镜下可见，比如细菌性抗原、红细胞抗原等；而可溶性抗原在光镜下不可见，如组织浸出液、细菌毒素、蛋白质分子等。
它们不等同于完全抗原和不完全抗原。完全抗原具有免疫原性和抗原性，而不完全抗原只具有抗原性。完全抗原可以是颗粒性抗原，亦可是可溶性抗原，而不完全抗原一般只能是可溶性抗原，不会是颗粒性抗原。
若已进入细胞内。则先由巨噬细胞吞噬降解。并形成抗原-MHC复合体传送到表面。被辅助性T淋巴细胞识别和效应T淋巴细胞识别后。效应T淋巴细胞被激活。分解靶细胞。然后再由效应B细胞分泌的抗体进一步消灭病毒。
还有不清楚的么？
