Assay Type
Detection Range
25 pg/ml -1600 pg/ml.
The minimum detectable dose of human A4GALT is typically less than 6.25 pg/ml.The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations.
Intra-assay Precision
Intra-assay Precision (Precision within an assay): CV%<8%. Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision
Inter-assay Precision (Precision between assays): CV%<10%. Three samples of known concentration were tested in twenty assays to assess.
Preparation and Storage
Unopened test kits should be stored at 2 to 8 degree C upon receipt. Please refer to pdf manual for further storage instructions.
ISO Certification
Manufactured in an ISO 9001:2008 Certified Laboratory.
Product Note
Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
Other Notes
Small volumes of A4GALT elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS901858 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the alpha 1, 4-galactosyltransferase (A4GALT) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing A4GALT. The ELISA analytical biochemical technique of the MBS901858 kit is based on A4GALT antibody-A4GALT antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect A4GALT antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, A4GALT. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

A4GALT elisa kit
Principle of the assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for A4GALT has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any A4GALT present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for A4GALT 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 A4GALT bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Summary for A4GALT
The protein encoded by this gene catalyzes the transfer of galactose to lactosylceramide to form globotriaosylceramide, which has been identified as the P(k) antigen of the P blood group system. The encoded protein, which is a type II membrane protein found in the Golgi, is also required for the synthesis of the bacterial verotoxins receptor. [provided by RefSeq, Jul 2008]
UniProt Comments for A4GALT
A4GALT: Necessary for the biosynthesis of the Pk antigen of blood histogroup P. Catalyzes the transfer of galactose to lactosylceramide and galactosylceramide. Necessary for the synthesis of the receptor for bacterial verotoxins. Belongs to the glycosyltransferase 32 family.
