|1.0 mg/mL of rabbit anti-B4GALT1 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 11220-R001)|
|0.5 mg/mL rabbit anti-B4GALT1 polyoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 300 ng of recombinant B4GALT1. 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 usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 10 ng/mL is recommended.|
|The minimum detectable dose of Human B4GALT1 was determined to be approximately 156 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
|The Human B4GALT1 ELISA Pair Set is for the quantitative determination of Human B4GALT1.|
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 B4GALT1 coated on a 96-well plate. Standards and samples are added to the wells, and any B4GALT1 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-B4GALT1 polyclonal 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 B4GALT1 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Beta1,4-Galactosyltransferase-I (B4GALT1), one of seven beta1,4-galactosyltransferases, is an enzyme commonly found in the trans-Golgi complex that adds galactose to oligosaccharides. They have an N-terminal hydrophobic signal sequence that directs the protein to the Golgi apparatus and which then remains uncleaved to function as a transmembrane anchor. By sequence similarity, the beta4GalTs form four groups: beta4GalT1 and beta4GalT2, beta4GalT3 and beta4GalT4, beta4GalT5 and beta4GalT6, and beta4GalT7. B4GALT1 gene directs production of B4GALT1 protein using either of two transcription start sites. The product of the smaller transcript serves the traditional biosynthetic role in the Golgi. This form also complexes with α-lactalbumin, a mammary-specific protein, to form lactose synthase. In addition to a biosynthetic role, the protein translated from the longer transcript appears on the plasma membranes of some cells where it serves as a signalling receptor in cell-matrix interactions such as sperm-egg binding.
