Handheld Gene Gun

SJ-500 Portable Gene Gun

The SJ-500 is a handheld biolistic particle delivery system (gene gun) designed for fast, on-site transformation of cells, tissues and live animal or plant material. A dedicated mechanism generates a regulated gas shock wave ranging from 0.5 to 5 MPa, using helium or nitrogen as the power source. Because this “cold” gas shock wave avoids the localized heating produced by “hot” gas systems, the SJ-500 limits sample damage while still delivering reliable, high-quality transgenic results.

Features

• High conversion rate – uniform particle dispersion combined with a convertible receptor design
• Convenient and portable – lightweight, hand-held design enables on-site transformation outside the lab
• High specificity – no unrelated genes or proteins are introduced into the sample
• Low sample requirements – low-input, vector-free processing with no DNA size limitation
• Versatile targeting – suitable for in situ, in vitro and in vivo bombardment

Technical Parameters

• Target area: approx. 2 cm² (small)
• Working pressure range: 0.5–5 MPa (12 shots per magazine revolution)
• Target type: animal cells, plant cells, living plant leaves, live animal skin, muscle and organs
• Power supply: 9 V (up to 1000 shots per battery)
• Gas source: helium or nitrogen
• Metal particles: Φ0.8–1.5 µm / Φ1.5–3.0 µm gold or tungsten powder
• Bombardment method: direct spotting from the magazine or nylon tube preparation

Standard System Configuration

Cutting machine, nylon tube magazine, sampling unit.
