Product Summary for HIV-1 Gag p24 Quantikine ELISA Kit

The Quantikine® QuicKit™ Human CD14 Immunoassay is a one step, 80-minute solid phase ELISA designed to measure human CD14 levels in cell culture supernates, serum, and plasma. It contains CHO-expressed recombinant human CD14 and antibodies raised against the recombinant protein. Results obtained for naturally occurring human CD14 showed linear curves that were parallel to the standard curves obtained using the recombinant QuicKit™ standards. These results indicate that this kit can be used determine relative mass values for natural CD14.

Precision

Intra-Assay Precision (Precision within an assay) Two samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Two samples of known concentration were tested in ten separate assays to assess inter-assay precision. Assays were performed by at least three technicians.

Recovery for HIV-1 Gag p24 Quantikine ELISA Kit

The recovery of human CD14 spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=4) 100 93-105
EDTA Plasma (n=4) 74 64-82
EDTA Plasma (ICD Treated) (n=4) 88 64-94
Heparin Plasma (n=4) 72 63-78
Heparin Plasma (ICD Treated) (n=4) 88 69-94
Serum (n=4) 79 73-85

Linearity

To assess the linearity of the assay, samples containing high concentrations of human CD14 were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.&nbsp;

Background: HIV-1 Gag p24

The gag gene of human immunodeficiency virus 1 (HIV-1) encodes a precursor protein known as Pr55Gag. The viral protease PR cleaves this precursor to generate p17, p24, p7, and p6 proteins which are required for virus particle assembly. p24 is a major viral core structural protein. Its measurement is commonly used as an indicator of HIV-1 infection and viral load.

Long Name

Human Immunodeficiency Virus Type 1 GAG/Group-specific Antigen core protein of 24 kDa

Alternate Names

CA, Capsid Protein, HIV1 Gag p24, Pr55(Gag)

Entrez Gene IDs

155030 (Viral)

Gene Symbol
