外观(性状)： Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
纯度： ≥95% as determined by reducing SDS-PAGE.
储存条件： Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
运输条件： 冷藏运输

背景说明： Semaphorin-4G is the least characterized of the seven known Class 4 transmembrane semaphorin glycoproteins.Class 4 semaphorins play multiple roles in cell attraction or repulsion，such as development of nerve pathways in the brain，promoting or inhibiting proliferation，in some cases organizing immune cell interactions.Semaphorin-4G can be expressed early in development in the central and peripheral nervous systems and in sensory ograns，such as cochlea，olfactory epithelium，vomeronasal organ and retina.In adults，Semaphorin-4G can be found in liver，kidney and brain.The human Semaphorin-4G precursor consists of a 17 amino acids signal sequence，a 658 amino acids extracellular domain，a 21 amino acids transmembrane domain，a 142 amino acids cytoplasmic domain with one Ser/Thr phosphorylation site.

溶剂： Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素： Less than 0.1 ng/ug(1 EU/ug)as determined by LAL test.Bio Activity:Measured in a cytotoxicity assay using L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D.The ED50 for this effect is 3.5 pg/ml.
