Laminin subunit beta-2 (LAMB2), partial, recombinant human

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1530-1798aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: PDSIEMVATR VLELSIPASA EQIQHLAGAI AERVRSLADV DAILARTVGD VRRAEQLLQD ARRARSWAED EKQKAETVQA ALEEAQRAQG IAQGAIRGAV ADTRDTEQTL YQVQERMAGA ERALSSAGER ARQLDALLEA LKLKRAGNSL AASTAEETAG SAQGRAQEAE QLLRGPLGDQ YQTVKALAER KAQGVLAAQA RAEQLRDEAR DLLQAAQDKL QRLQELEGTY EENERALESK AAQLDGLEAR MRSVLQAINL QVQIYNTCQ. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. Relevance: Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during bryonic development by interacting with other Extracellular domain matrix components. Reference: Human laminin beta2 deficiency causes congenital nephrosis with mesangial sclerosis and distinct eye abnormalities.Zenker M., Aigner T., Wendler O., Tralau T., Muentefering H., Fenski R., Pitz S., Schumacher V., Royer-Pokora B., Wuehl E., Cochat P., Bouvier R., Kraus C., Mark K., Madlon H., Doetsch J., Rascher W., Maruniak-Chudek I. , Lennert T., Neumann L.M., Reis A.Hum.

Function: Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components.
