Human Leucine-rich repeat-containing protein 4B (LRRC4B) ELISA Kit

LRRC4B is a synaptic adhesion protein. It regulates the formation of excitatory synapses. The trans-synaptic adhesion between LRRC4B and LAR regulates excitatory synapse formation in a bidirectional manner. LRRC4 are post-synaptic adhesion molecules of the LRR protein family that induce excitatory synapse formation. Mature LRRC4 family members are type I transmembrane proteins with an extracellular region that contains nine LRRs, a C2-type Ig-like domain, and a Thr-rich segment. LRRC4 family members share ~55% aa identity, but each recognizes different ligands. LRRC4 and LRRC4C recognize Netrin-G2 and Netrin-G3, respectively, while LRRC4B recognizes the receptor tyrosine phosphatases LAR/PTPRF, PTPR delta and PTPR sigma.

Human Leucine-rich repeat-containing protein 4B (LRRC4B) ELISA Kit has high sensitivity and excellent specificity for detection of Human LRRC4B. No significant cross-reactivity or interference between Human LRRC4B and analogues was observed.

This Human Leucine-rich repeat-containing protein 4B (LRRC4B) ELISA Kit employs a two-site sandwich ELISA to quantitate LRRC4B in samples. An antibody specific for LRRC4B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLRRC4B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LRRC4B is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LRRC4B bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
