background |
MHC class I polypeptide-related sequence A, also known as MIC-A, PERB11.1 and MICA, is a single-pass type I membrane protein which belongs to the MHC class I family of MIC subfamily. MICA contains one Ig-like C1-type domain and is expressed on the cell surface, although unlike canonical class I molecules does not seem to associate with beta-2-microglobulin. It is thought that MICA functions as a stress-induced antigen that is broadly recognized by NK cells, NKT cells, and most of the subtypes of T cells. MICA is the ligand for NK cell activating receptor KLRK1/NKG2D. MICA seems to have no role in antigen presentation. MICA leads to cell lysis by binding to KLRK1. |
description |
Recombinant Human MHC Class I Polypeptide-Related Sequence A is expressed by our Mammalian expression system and the target gene encoding Ala23-Glu308 is expressed with a Fc tag at the C-terminus. |

purity |
>95% as determined by reducing SDS-PAGE. |
endotoxin |
<0.1 ng/µg (1 EU/µg) as determined by LAL test. |
bioactivity |
Measured by its ability to bind Human N2DL2 in functional ELISA. The ED50 for this effect is less than 5 ug/ml. |
formulation |
Recombinant Human MICA Protein was lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
reconstitution |
Dissolve the lyophilized protein in distilled water. |
usage |
For Research Use Only |
storage |
Human MICA protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
