Key Properties

• Source: Human
• Biological Origin: Human
• Target: COL4A1-COL4A6
• Purity: This product has been prepared from human placenta and is chromatographically and immunologically pure. This product is free from other collagens, human serum proteins and non-collagen extracellular matrix proteins. This product reacts with anti-Collagen Type IV. Reaction with anti-Collagen I, II, III, V or VI is negligible (typically less than 1% cross-reactivity was detected by ELISA).
• Conjugation: Unconjugated

Storage & Handling

• Storage: Store vial at 4° C prior to opening. This product is stable at 4° C as an undiluted liquid. Dilute only prior to immediate use.
• Form/Appearance: Liquid (sterile filtered)
• Buffer/Preservatives: 0.01% (w/v) Sodium Azide
• Concentration: 1.0 mg/ml
• Disclaimer: For research use only
