产品数据评论相关产品实验方法
 CD244 组成成分
包被抗体:0.5 mg/mL of rabbit anti-2B4 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 10042-R025)
检测抗体:0.25 mg/mL rabbit anti-2B4 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4). Dilute to working concentration of 0.0625 μg/mL in detection antibody dilution buffer before use. (Catalog: # 10042-R031)
标准品:Each vial contains 56 ng of recombinant 2B4. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 8 ng/mL is recommended.
 CD244 检测灵敏度
The minimum detectable dose of Human 2B4 / CD244 was determined to be approximately 125 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
 CD244 产品介绍
The Human 2B4 / CD244 ELISA Pair Set is for the quantitative determination of Human 2B4 / CD244.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for 2B4 / CD244 coated on a 96-well plate. Standards and samples are added to the wells, and any 2B4 / CD244 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-2B4 / CD244 monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of 2B4 / CD244 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
 CD244 储存方法
