  • MACROCYCLIC TETRAPYRROLE COMPOUNDS, COMPOSITIONS AND METHODS FOR INCREASING ABIOTIC STRESS RESISTANCE IN PLANTS
    Publication number: 20210352889
    Abstract: A method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying to the plant a combination including: a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and an oil selected from the group consisting of a mineral oil, a vegetable oil and a mixture thereof. Another method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof, to at least one of a seed and a seedling of the plant.

  • Tetrameric streptavidin mutein with reversible biotin binding capability
    Patent number: 8822640
    Abstract: The present invention relates to a new streptavidin muteins. This mutein is The muteins are capable of oligomerization to form tetramers, with relatively strong subunit interactions, dissociation constant (KD) for biotin in this mutein in the range of 10?7 to 10?8M, off-rate (koff) for the bound biotin in the streptavidin-biotin complex in the range of 10?4 sec?1, stable enough to allow reuse, and producible producable with reasonable production yield via secretion in a soluble functional state without the requirement of refolding streptavidin via the tedious and expensive denaturation and renaturation processes.
