Human chorionic gonadotropin (HCG) enzyme-linked immunosorbent assay (ELISA) kit instructions for use? This kit is for research use only. This kit is used to quantify the amount of chorionic gonadotropin (HCG) in human serum, plasma and related fluid samples in vitro. Validity: 6 months? Storage conditions: 2-8 °C experimental principle This kit uses the double antibody sandwich method to determine the level of human chorionic gonadotropin (HCG) in the specimen. The microporous plate was coated with purified human chorionic gonadotropin (HCG) antibody to prepare a solid phase antibody, and chorionic gonadotropin (HCG) was sequentially added to the microcapsules of the coated monoclonal antibody, followed by HRP-labeled fluff. The membrane gonadotropin (HCG) antibody binds to form an antibody-antigen-enzyme-labeled antibody complex, which is thoroughly washed and then added to the substrate TMB for color development. TMB is converted to blue under the catalysis of HRP enzyme and converted to the final yellow color by the action of an acid. The color depth is positively correlated with chorionic gonadotropin (HCG) in the sample. The absorbance (OD value) was measured with a microplate reader at a wavelength of 450 nm, and the concentration of human chorionic gonadotropin (HCG) in the sample was calculated from a standard curve.

Turnstile Gate
Turnstile gates are a kind of passage blocking device (passage management equipment), mainly used in urban rail transit management, used to manage the flow of people and regulate pedestrian access.
According to the difference in the number of core and arresting bodies contained in the same gate, the gate can be divided into single core (including 1 core and 1 arresting body) and double cores (including 2 cores and 2 arresting bodies in a symmetrical form). According to the difference of the blocking body and the blocking method, it can be divided into Tripod Turnstile Gate, Swing Turnstile Gate, Flap Turnstile Gate, speed turnstile gate, full turnstile gate, Sliding Turnstile Gate, etc.
Our factory has a complete production line of turnstiles and a strong supply capacity. The products are exported to 256 countries and regions.
