Preparation and Storage
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
ISO Certification
Manufactured in an ISO 9001:2008 and ISO 13485:2003 Certified Laboratory.
Supply Chain Verification
Manufactured in a lab with traceable raw materials. Bulk orders can typically be prepared to the customer’s specifications, please inquire.
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 DHCR7 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.
Searchable Terms for DHCR7purchase
MBS2019907 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the 7-Dehydrocholesterol Reductase (DHCR7) 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 DHCR7. The ELISA analytical biochemical technique of the MBS2019907 kit is based on DHCR7 antibody-DHCR7 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect DHCR7 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, DHCR7. 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(%).

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to 7-Dehydrocholesterol Reductase (DHCR7). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to 7-Dehydrocholesterol Reductase (DHCR7). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain 7-Dehydrocholesterol Reductase (DHCR7), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of 7-Dehydrocholesterol Reductase (DHCR7) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

NCBI Summary for DHCR7
This gene encodes an enzyme that removes the C(7-8) double bond in the B ring of sterols and catalyzes the conversion of 7-dehydrocholesterol to cholesterol. This gene is ubiquitously expressed and its transmembrane protein localizes to the endoplasmic reticulum membrane and nuclear outer membrane. Mutations in this gene cause Smith-Lemli-Opitz syndrome (SLOS); a syndrome that is metabolically characterized by reduced serum cholesterol levels and elevated serum 7-dehydrocholesterol levels and phenotypically characterized by mental retardation, facial dysmorphism, syndactyly of second and third toes, and holoprosencephaly in severe cases to minimal physical abnormalities and near-normal intelligence in mild cases. Alternative splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Aug 2009]
UniProt Comments for DHCR7
DHCR7: Production of cholesterol by reduction of C7-C8 double bond of 7-dehydrocholesterol (7-DHC). Defects in DHCR7 are the cause of Smith-Lemli-Opitz syndrome (SLOS); also known as SLO syndrome or RSH syndrome. SLOS is an autosomal recessive frequent inborn disorder of sterol metabolism with characteristic congenital malformations and dysmorphias. All patients suffer from mental retardation. Children with SLOS have elevated serum 7-dehydrocholesterol (7- DHC) levels and low serum cholesterol levels. SLOS occurs in relatively high frequency: approximately 1 in 20,000 to 30,000 births in populations of northern and central European background. Historically, a clinical distinction often was made between classic ('type I') SLOS and the more severely affected ('type II') patients. There is, in reality, a clinical and biochemical continuum from mild to severe SLOS. Belongs to the ERG4/ERG24 family.
