Product Description
LS-F10113 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human EGFR in samples of Plasma, Serum and Tissue Homogenates. It is based upon a Sandwich assay principle and can be used to detect levels of EGFR as low as 0.019 nanograms per millilter.More EGFR Products

Specifications
TypeSandwich ELISA (enzyme-linked immunosorbent assay) kit
Target
EGFR
Synonyms
EGFR, EGF Receptor, ERBB, ERBB1, MENA, PIG61, Proto-oncogene c-ErbB-1, V-erb-b homolog, EGF-R, HER1
Reactivity
Human
Specificity
This assay has high sensitivity and excellent specificity for detection of human EGFR. No significant cross-reactivity or interference between human EGFR and analogs was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between human EGFR and all the analogs, therefore, cross reaction may still exist.

Quality Assurance
Due to their limited shelf life, LSBio ELISA kits are not typically stocked as finished goods. Upon receipt of an order each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Range, Sensitivity, and Precision. In the event of a significant change the order would be confirmed with the customer before shipping ELISA kit lot numbers reflect the date of final assembly and testing for each specific kit rather than a bulk manufactured lot. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation.

Background
This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for EGFR has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any EGFR present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for EGFR is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of EGFR bound in the initial step. The color development is stopped and the intensity of the color is measured.
Restrictions
For research use only.
Guarantee
This elisa kit carries the LSBio 100% Guarantee.
About EGFR
Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, amphiregulin, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. P00533 NM_005228 NP_005219.2

文献和实验有替代前者的趋势。由于ABS-ELISA较普通ELISA多用了两种试剂,增加了操作步骤,在临床检验中ABS-ELISA应用不多。科研项目中检测微量的成分如细胞因子常采用本法。晶美分装ELISA KIT采用的方法:1, TORCH及传染病试剂盒(间接法),见2.2.32, TORCH-IgM捕获法特色:包被抗体,标记抗原原理:3, 细胞因子试剂盒采用的方法路线(ABC-ELISA)原理产品特色:采用ABC法,灵敏度更高,特异性更强。生物素抗体和酶联物是浓缩的,使用前需用相应的缓冲液稀释。酶联物可以通用
的原理用于分子诊断方面:TrimGen公司的KRAS Mutation Detection Kit在96孔板里一次能实现7/8个KRAS突变位点的检测。 另外基于相同原理的技术还有PPT-ELISA。这是用来筛截短突变的,相关文章见:1,Rapid screen for truncating ATM mutations by PTT-ELISA . 2,An ELISA-based high throughput protein truncation test
yan0495 R&D公司的recombinant human EGF Receptor来源于DNA编码的人类EGFR的胞外区,而酪氨酸激酶活性区在胞内,我现在需要做酪氨酸激酶抑制剂的筛选,不知道能不能用这个蛋白?筛选原理: 以多聚酪氨酸多肽为底物,用EGFR催化酪氨酸的磷酸化,用酶标记的单克隆抗体检测酪氨酸磷酸化程度,以OPD做为辣根过氧化物酶底物显色,从而筛选EGFR抑制剂。附上EGFR说明书和图。 请各位指点啊! yan
