Description

Auxiliary positioning template Technical Field The utility model relates to the field of biomedical experiment auxiliary tools, in particular to an auxiliary positioning and template. Background In Western blot (Western immunoblotting) experiments, protein electrophoresis gel sample adding is one of key steps, operation accuracy directly influences subsequent electrophoresis separation effect and result analysis, in the protein electrophoresis link of the experiments, glass plates are key equipment used in the gel preparation process (gel preparation) and are usually used in pairs, two plates are fixed together through gel preparation clamps or clamps to form a sandwich structure with sealed bottoms and two sides, a gel interlayer is arranged in the middle, and the top opening is used for pouring gel solution into the interlayer. Current Western blot experiment situation: (1) The protein electrophoresis sample adding operation usually adopts manual positioning, an experimenter aims at a sample adding hole with naked eyes, the sample adding precision depends on personal experience, but the manual positioning has strong subjectivity and sample adding deviation; (2) The glass plate has no mark, is easy to cause inaccurate sample adding and sample leakage, or adopts a sticker/hand drawing mark, but has the defects of easy falling, washing fastness and poor repeatability; (3) Porous samples are not numbered in operation, and unordered loading easily causes sample confusion and difficult recording. The hole site can be formed by the aid of the glue making comb, but after the comb is pulled out, visual reference is lacking, glue and glass are easy to misplacement, and the alignment of the sample hole is easy to be caused, so that a sample adding plate with the auxiliary positioning and number representing functions is needed to be provided so as to solve the problems. Disclosure of utility model The utility model aims to overcome the defects in the prior art, and provides an auxiliary positioning template, wherein the tooth protrusions on the side surface of the template are used for being clamped with tooth grooves of a glue making comb, so that the positioning of the glue making comb in the glue making process is realized, and the accurate correspondence of the hole positions of the sample feeding holes can be ensured after the glue making comb is taken out, and the dislocation can not occur. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides an assistance-localization real-time adds the template, includes the application of sample mainboard, one side of application of sample mainboard is provided with and is used for embedding the system to glue the tooth that the comb corresponds the tooth's socket and abrupt, the tooth abrupt follow straight line equidistance interval distribute in the application of sample regional edge on application of sample mainboard upper portion, just the system is glued the broach of comb and is corresponded and imbeds adjacent two in the clearance of tooth abrupt.
