Figure 10 is the synoptic diagram that detects two samples on biochip of the present invention simultaneously.
Figure 11 is the enlarged drawing of two samples among Figure 10.
Referring to Fig. 1 to Fig. 3, the present invention is a kind of multiple-sample microarray biochip, and its solid substrate is a solid phase carrier with the microslide form.Microslide 1 is a kind of solid sheet glass sheet, and its size is identical with standard microscope slide, is 25mm * 75mm * 0.96mm.
The surface of microslide 1 be provided with separate to be provided with and the chamber 2 of seepage mutually not, it is surperficial and form that this chamber 2 is pasted on microslide 1 by the grid-like single face glue material 3 of one deck.One deck mylar 4 is pasted on surface at grid-like single face glue material 3 again, so that above-mentioned chamber 2 is airtight.Can adhesive label in microslide 1 blank space that does not post single face glue material 3 and mylar 4, this blank space is the place 5 that labels of microslide 1.
The size of grid-like single face glue material 3 is 50mm * 25mm, to cooperate the size of microslide.The thickness of grid-like single face glue material 3 is 1mm at least, is 1mm～3mm, and wherein one side has viscosity, can with microslide 1 surperficial close adhesion, and its surface is separated into not the little chamber 2 of seepage mutually.This single face glue material 3 is immersed in the water and can dissolve, and also can bear certain water impact, therefore be pasted on microslide 1 after, can stand the cleaning of current and can not be out of shape, seepage.After experiment finished, this single face glue material 3 will be removed, so that use chip scanner that chip is detected and analyzes.
Mylar 4 is used to stick on the surface of grid-like single face glue material 3.The one side of mylar 4 has viscosity, can stick on single face glue material 3 noncohesive one sides, to reach the effect that chamber 2 is airtight.The viscosity of mylar 4 is lower than single face glue material 3, can more easily be removed and does not influence the stickup of single face glue material 3 and microslide 1.The single face glue material 3 that sticks on the microslide 1 is capped after the stickup mylar 4, form the little airtight chamber 2 of mutual isolation, had no cross pollution between the chamber 2, and reduced liquid evaporation, can on shaking table, shake fully and react, improve the accuracy of reaction thus.
The length of side of each chamber 2 is the multiple of 3mm.Chamber 2 is set to 1 * 2 to 4 * 10, comprises 1 * 2, and 1 * 3,2 * 3,2 * 5,3 * 5,3 * 8,3 * 10,4 * 8, or the like.The spacing at adjacent two chamber centers of chamber 2 is the multiple of 4.5mm, consistent with conventional 384 orifice plates or 96 orifice plates that use in laboratory, the rifle head spacing (9mm) that can cooperate multiple gun head application of sample rifle, also the spotting needle spacing (multiple of 4.5mm) with Linomat device people is consistent, is convenient to application of sample, point sample operation.
As Fig. 1, Fig. 8 and shown in Figure 9, the spacing at adjacent two chamber centers of chamber 2 is 4.5mm.
As Fig. 5, Fig. 6 and shown in Figure 7, the spacing at adjacent two chamber centers of chamber 2 is 9mm.
As shown in Figure 4, the spacing at adjacent two chamber centers of chamber 2 is 18mm.The spacing at adjacent two chamber centers of chamber 2 also can be 13.5mm.
For example: the chamber length of side is 3mm, and the center distance of two adjacent chamber then is 4.5mm.The chamber length of side is 6mm, and the center distance of two adjacent chamber then is 9mm.The chamber length of side is 9mm, and the center distance of two adjacent chamber then is 13.5mm.The chamber length of side is 12mm, and the center distance of two adjacent chamber then is 18mm.
Be furnished with the micro probe array point in each chamber 2, can finish multiple reaction simultaneously, promptly in each chamber 2, finish multiple reaction simultaneously.In experiment, save sample, the most only needed 5 μ l can finish analyzing and testing.
Multiple-sample microarray biochip of the present invention is used for western hybridization, nucleic acid (DNA (deoxyribonucleic acid) DNA or RNA (ribonucleic acid)) hybridization, DNA (deoxyribonucleic acid) (DNA) amplification.Entire chip can be born up to 97 ℃ of temperature, bears-40 ℃ low temperature, can tolerate ultraviolet and handle, and stands current and cleans.
Referring to Figure 10 and Figure 11, on a multiple-sample microarray biochip of the present invention, detect two samples simultaneously, left chamber shows this example reaction positive, right chamber then shows another example reaction feminine gender.
Multiple-sample microarray biochip making of the present invention and use are as follows:
1, the paper that uses tweezers will cover on the sub-single face glue material is peeled off gently, and careful covering of one side that single face glue material is had viscosity is pasted on the microslide, notes keeping the microslide clean dried during stickup, and notes not allowing bubble enter stickup face.Microslide is turned over, place clean plane, beat microslide, make it to paste tightr with the tweezers back of the body.
2, determine dot matrix and square formation in each chamber according to the project of required detection, and use spotting robot to carry out point sample according to designed dot matrix and square formation.
3,, in each chamber, add different samples and reaction reagent according to reaction needed and reaction conditions.
4, carefully with the sticking one side of mylar tape, begin fitly to be pasted on the surface of single face glue material from a side of single face glue material, reaction such as can hatch.
5, after question response finishes, mylar is torn, can clean; As need application of sample again, then behind application of sample, paste one deck mylar again, proceed reaction.
6, when respond finish after, at last single face glue material is removed promptly available chip scanner observations.Can cut lightly with blade when removing single face glue material, operation can be more convenient like this.
