Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Usage: No attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution For all practical purposes, each ampoule contains the same quantity of VEGF165. The entire contents of each ampoule should be completely dissolved in a known volume of suitable solvent. It is recommended that, when possible, buffer containing carrier protein should be used to minimize loss by surface adsorption. The solvent should be compatible with the assay system used.
