Abstract
Applicator devices for depositing a fluid sample onto a substrate, as well as methods for their use, are provided. The subject devices are elongate in shape and have a first end and a second end. The first end has a planar surface of substantially circular shape with a conical protuberance arising therefrom. The second end may have a means for attaching to an automated movement means. In using the subject devices, the first end is dipped into a fluid sample and then contacted with the surface of a substrate in a manner sufficient to deposit a fluid sample onto the substrate surface. The subject devices and methods find use in a variety of different applications, particularly in the preparation of biopolymeric arrays.
Claims14
An applicator device for depositing a fluid sample onto the surface of a substrate, said device comprising:
- an elongate member with a first end and a second end, wherein said first end is characterized by the presence of a substantially planar surface having a diameter ranging from about 0.1 mm to 2.0 mm and a solid conical protuberance arising therefrom having a height that ranges from about 0.05 to about 0.2 mm and a diameter that is at least 5 fold less than the diameter of said substantially planar surface.
An applicator device for depositing a fluid sample in a substantially uniform circular spot on the surface of a substrate, said device comprising:
- an elongate member with a first end and a second end separated by three different regions of different dimensions, wherein said first end is characterized by the presence of a substantially circular planar surface having a diameter ranging from about 0.1 mm to 2.0 mm and a solid conical protuberance arising therefrom having a height that ranges from about 0.05 to about 0.2 mm and a diameter that is at least 5 fold less than the diameter of said substantially circular planar surface and said second end is characterized by the presence of a means for attaching to an automated movement means.
