Mini Sample Mouse BLC (B-Lymphocyte Chemoattractant) ELISA Kit (E-MSEL-M0114)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to BLC . Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for BLC and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain BLC , biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of BLC . You can calculate the concentration of BLC in the samples by comparing the OD of the samples to the standard curve.

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.
