MICB Protein, Human (HEK293, His)

MICB Protein, a heavily glycosylated ligand for NKG2D receptor, triggers cytolytic response in immune cells. It resembles MHC class I molecules but lacks association with beta-2-microglobulin or peptide binding. Alternative splicing leads to multiple transcript variants. MICB is widely expressed, especially in lymph nodes and bone marrow, highlighting its immune response role in diverse physiological contexts. MICB Protein, Human (HEK293, His) is the recombinant human-derived MICB protein, expressed by HEK293 , with C-His, C-6*His labeled tag. The total length of MICB Protein, Human (HEK293, His) is 276 a.a., with molecular weight of ~45 kDa.

MICB encodes a heavily glycosylated protein that serves as a ligand for the NKG2D type II receptor. Upon binding, this ligand triggers the cytolytic response of various immune cells, including natural killer (NK) cells, CD8 alphabeta T cells, and gammadelta T cells expressing the receptor. Notably, MICB is stress-induced and shares similarities with MHC class I molecules, although it does not associate with beta-2-microglobulin or bind peptides. Alternative splicing generates multiple transcript variants, adding to the complexity of its functional repertoire. The expression of MICB is broad, with notable presence in lymph nodes, bone marrow, and various other tissues, underscoring its role in immune responses across diverse physiological contexts.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<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. 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.
