store lyophilized/reconstituted at -20°C, once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
NRT1.1 (nitrate transporter 1.1) is a dual-affinity nitrate transporter which acts also as a nitrate sensor. High-affinity nitrate transporter when phosphorylated and low-affinity transported when dephosphorylated. Low nitrogen concentration stimulates phosphorylation. Expressed in lateral roots. Alternative names: AtNRT1, Nitrate/chlorate transporter, protein CHLORINA 1, AtNPF6.3.
