A synthetic peptide corresponding to a sequence at the N-terminus of human NRP2(45-60aa YPQDYPSHQNCEWIVY), identical to the related mouse sequence and different from the related rat sequence by one amino acid.
The powdered antibody should be dissolved in 0.2 ml of distilled water to achieve final concentration of 500ug/ml
Storage condtions
Keep the NRP2 Antibodyat minus twenty degrees Celsius for 1 year. The ready-to-use solutions can be stored at four degrees Celsius for a month. Our specialsits recommend to freeze the aliquotes at minus twenty degrees Celsius for long-term application. Multiple procedures of freezing and thawing influence the specifity and reactivity of the antibody in a negative way.
Tips
The NRP2 Antibody did not cross-reacted with other proteins during the test procedures. This antobdy is intended to be used for research analyses and it is not applicale for in vitro diagnostics.
Background
NRP2(Neuropilin-2), also called Npn2 or VEGF165R2, encodes a member of the neuropilin family of receptor proteins. The soluble NRP2 was secreted as a 62.5-kD protein following transfection in Chinese hamster ovary cells. The NRP2 gene is mapped on 2q33.3. The NRP2 gene contains 17 exons and spans about 112 kb. Sema3b can act to repulse axons expressing neuropilin-2 and can antagonize the repulsive action of Sema3a on axonal growth cones expressing neuropilin-1. This protein may play a role in cardiovascular development, axon guidance, and tumorigenesis. Mice with null mutations in genes encoding Sema3F, and its holoreceptor components Npn2 and plexin A3(PLEXA3), exhibit increased dentate gyrus granule cell and cortical layer V pyramidal neuron spine number and size, and also aberrant spine distribution. Moreover, Sema3F promotes loss of spines and excitatory synapses in dissociated neurons in vitro, and in Npn2-null brain slices cortical layer V and dentate gyrus granule cells exhibit increased miniature excitatory postsynaptic current frequency. These disparate effects of secreted semaphorins are reflected in the restricted dendritic localization of Npn2 to apical dendrites and of Npn1 to all dendrites of cortical pyramidal neurons.
