特異性：This item recognises alpha A crystallin, a 20kDa water-soluble major structural protein and member of the heat shock protein family, designated HSPB4, which acts as a molecular chaperone and is believed to play a role in the maintenance of ocular lens transparency/refractive index. Besides the involvement of both alpha A and alpha B crystallin in the prevention of protein precipitation and cataract formation in the eye, alpha crystallins have also been demonstrated in other tissues including the heart, brain, kidney, spleen and thymus.
