LRP-1 Cluster IV Protein, Human (CHO, His)

LRP-1 Cluster IV Protein is involved in endocytosis and phagocytosis of apoptotic cells. The LRP-1 Cluster IV Protein also serves as a receptor for Pseudomonas aeruginosa exotoxin A during microbial infection. LRP-1 Cluster IV Protein, Human (CHO, His) is the recombinant human-derived LRP-1 Cluster IV protein, expressed by CHO , with C-10*His labeled tag.

LRP-1 Cluster IV Protein emerges as a multifunctional endocytic receptor, playing pivotal roles in both endocytosis and the phagocytosis of apoptotic cells. Its significance extends to essential functions in early embryonic development and cellular lipid homeostasis. Additionally, LRP-1 Cluster IV is actively involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the localized metabolism of complexes formed between plasminogen activators and their endogenous inhibitors. Acting as an LRPAP1 alpha-2-macroglobulin receptor, it further participates in various cellular events, including the endocytosis and subsequent spread of TAU/MAPT. Moreover, LRP-1 Cluster IV may modulate critical cellular processes such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling, and neurotransmission. Notably, in microbial infection, the protein functions as a receptor for Pseudomonas aeruginosa exotoxin A, highlighting its diverse and intricate roles in cellular physiology and host-pathogen interactions.

Measured by its binding ability in a functional ELISA. Immobilized Human LRP-1 Cluster IV at 1 μg/mL (100 μL/well) can bind Biotinylated Human LRPAP1. The ED₅₀ for this effect is 1.235 ng/mL.

Partial

Approximately 60-88 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
