AP-4 complex subunit sigma-1 (AP4S1), ELISA Kit

For Research Use Only. Not for use in diagnostic procedures.

Store all reagents at 2-8 degree C.

We suggest pre-experimenting with neat (undiluted) samples, 1:2 or 1:4 dilutions. Please avoid diluting your samples more than 1:10 as it would exceed the dilution limit set for this kit. If the expected concentration of the target is beyond the detection range of the kit, please contact our technical support team

Select online data sheet information is drawn from bioinformatics databases, occasionally resulting in ambiguous or non-relevant product information. It is the responsibility of the customer to review, verify, and evaluate the information to make sure it matches their requirements before purchasing the kit. 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.

Small volumes of AP4S1 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.

MBS7203604 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the AP-4 complex subunit sigma-1 (AP4S1) 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 AP4S1. The ELISA analytical biochemical technique of the MBS7203604 kit is based on AP4S1 antibody-AP4S1 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect AP4S1 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, AP4S1. 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(%).

AP4S1_HUMAN

This gene encodes a member of the adaptor complexes small subunit protein family. These proteins are components of the heterotetrameric adaptor protein complexes, which play important roles in the secretory and endocytic pathways by mediating vesicle formation and sorting of integral membrane proteins. The encoded protein is the small subunit of adaptor protein complex-4, which is associated with both clathrin- and nonclathrin-coated vesicles. Mutations in this gene are associated with spastic quadriplegic cerebral palsy-6. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6.

AP4S1: Subunit of novel type of clathrin- or non-clathrin- associated protein coat involved in targeting proteins from the trans-Golgi network (TGN) to the endosomal-lysosomal system. Defects in AP4S1 are the cause of cerebral palsy spastic quadriplegic type 6 (CPSQ6). CPSQ6 is a neurodevelopmental disorder characterized by neonatal hypotonia that progresses to hypertonia and spasticity, and severe mental retardation with poor or absent speech development. Belongs to the adaptor complexes small subunit family. 2 isoforms of the human protein are produced by alternative splicing.
