A breakthrough in the field of biology and bioluminescence started in the 60s with the discovery of a glowing protein obtained from the jellyfish Aequorea victoria by Osamu Shimomura and colleagues. However, it was only in the early 90s when the green fluorescent protein (GFP) sequence was cloned and used inside a foreign organism as a fluorescent marker. Today more than 800 entries of various fluorescent proteins can be found in an open-source database with the most currently available variants here.

Our sdAbs bind strongly to most of the fluorescent proteins derived from Aequorea Victoria; check our specificity chart in the resources section.

Formulation: DBCO and biotin conjugated sdAbs (1:1 labeling on the c-term.) are lyophilized from PBS pH 7.4. Unconjugated sdAbs are lyophilized from 10 mM KPi,150 mM NaCl, 1 mM EDTA pH 6.0. Reconsitute with 250 µL pure water for immediate use or with 250 µL 50% glycerol for storage at -80 °C. The N0305-HRP is lyophilized from 200 µL HRP protector buffer and should be reconstituted with 200 µL pure deionized water and stored at 4°C.

Ext Coef: 24138
Shipping: Ambient temperature
Storing: Vials containing lyophilized protein can be stored at 4°C for upto 6 months. Vials containing reconstituted protein should be stored at -20°C or below.

Western Blotting not recommended. The sdAbs tend to recognize native protein conformation only.
