Product Summary
The Quantikine Human BLC/BCA-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human BLC/BCA-1 in cell culture supernates, serum, plasma, and saliva. It contains E. coli-expressed recombinant human BLC/BCA-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human BLC/BCA-1 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring BLC/BCA-1.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

The recovery of natural BLC/BCA-1 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 98 87-110
EDTA Plasma (n=4) 99 92-107
Heparin Plasma (n=4) 101 92-115
Serum (n=4) 99 86-108
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of natural BLC/BCA-1 were serially diluted with the Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: CXCL13/BLC/BCA-1
CXCL13/BLC/BCA-1 is a constitutively expressed chemokine that plays an important role in B and T cell homing. It is expressed by salivary gland epithelium, dendritic cells, osteoclasts, and peritoneal macrophages. It can form homodimers or heterodimers with FGF basic, and it signals through CXCR3 or CXCR5. CXCL13 induces the migration of naïve B cells and a subset of memory T cells to lymphoid tissue. It also promotes B1 cell migration into the omentum and peritoneum. In the fetus, CXCL13 attracts CD4+ CD3- IL-7 R alpha+ hematopoietic cells to sites of future Peyer’s patch development.
