Product Note
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.
Other Notes
Small volumes of HTATSF1 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.

MBS9338886 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the HIV-1 Tat specific factor 1 (HTATSF1) 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 HTATSF1. The ELISA analytical biochemical technique of the MBS9338886 kit is based on HTATSF1 antibody-HTATSF1 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect HTATSF1 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, HTATSF1. 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(%).

NCBI Summary for HTATSF1
The protein encoded by this gene functions as a cofactor for the stimulation of transcriptional elongation by HIV-1 Tat, which binds to the HIV-1 promoter through Tat-TAR interaction. This protein may also serve as a dual-function factor to couple transcription and splicing and to facilitate their reciprocal activation. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Sep 2009]
UniProt Comments for HTATSF1
TAT-SF1: Functions as a general transcription factor playing a role in the process of transcriptional elongation. May mediate the reciprocal stimulatory effect of splicing on transcriptional elongation. In case of infection by HIV-1, it is up-regulated by the HIV-1 proteins NEF and gp120, acts as a cofactor required for the Tat-enhanced transcription of the virus. Belongs to the HTATSF1 family.

Protein type: Spliceosome; Transcription, coactivator/corepressor

Chromosomal Location of Human Ortholog: Xq26.3

Cellular Component: nucleoplasm; nucleus

Molecular Function: nucleotide binding

Biological Process: regulation of transcription from RNA polymerase II promoter; transcription, DNA-dependent; viral genome replication; regulation of RNA elongation
