Hi, all I have crystals of a membrane protein. They are rectangular plate shape. When I shoot x-ray beam perpendicular to the plate, it diffracts up to 3.2A, but when I shoot x-ray beam parallel to the plate it diffracts with significant anisotropic pattern. All of the crystals show this. I have attached a ppt file for reference. Could anyone help me? Have a great day. Myeongseon Lee
