Abstract: Candidiasis or infection that is caused by Candida has become a new list of the therapeutical problems recently. The difficulties in diagnosing are the main cause of the unsatisfactory results from common therapies and diagnosis methods. This has urged researchers to find alternative ways in candidiasis diagnosis such as serology-based detection using antigen or antibody development. The aim of this study was to evaluate the potential of protein derived from Candida albicans biofilm as bioreceptor on candidiasis immunoassay through Dot Blot method. The research method used descriptive method with the following stages: (1) preparation of Candida albicans biofilm (2) extraction of Candida albicans protein through enzymatic and mechanical methods, (3) determination of protein molecular weight with SDS-PAGE (4) production of polyclonal anti- candida and (5) analysis of protein extract as bioreeceptor on dot blot. Profile of biofilm proteins on SDS-PAGE analysis were shown on molecular weight 27,42; 29,89; 38,10; 44,90; 48,75; 52,92; 55,14; 59,86; 70,56; 87,36; 102,54;115,05; 130,14;143,14;181,53 kD. There were differences in the intensity of dots in the control group (44070) and treatment groups (63170.5). It is noticeable that biofilm protein extract of C. albicans can be used for induction of anti-Candida polyclonal antibody production as the potential candidate of bioreceptor in candidiasis immunoassay. Keywords: SDS-PAGE, polyclonal antibody, immunoassay, dot blot, biofilm

Herb Phyllanthus niruri (P. niruri) is known to have various pharmacological functions including anticancer, antibacterial, antioxidant, anti-hypertensive and also anti-diabetic properties.  In this research, the proteomic part of P. niruri was studied to determine the bioactive peptides that responsible for specific characteristics. Total soluble proteins from different plant parts of freshly collected P. niruri were extracted using TCA/acetone method and then quantified using Bradford assay. Fruits part was found to have a significantly higher amount of proteins (4.91µg/µl + 0.21) compared to leaves (4.18µg/µl + 0.15). To determine the quality of proteins in the crude extract, SDS-Page was carried out which separates proteins in the basis of molecular weight. Proteins extracted from leaves were widely distributed between the range of 3.5 kDa to 160 kDA. Meanwhile, proteins in fruits mainly distributed within the range of 15 kDa to 80 kDa. The most highly expressed protein band was found in fruit, located in between 30 to 40 kDa. The protein extracts were then further analyzed based on the molecular weight and isoelectric points using two-dimensional gel electrophoresis (2D-GE) approach. Based on the profile pattern obtained from 2D-GE analysis, protein extract from fruits seems to express more protein spots compared to protein extract from leaves. Protein spots from fruit are seen to be intensely resolved within pH 4 to 10 at molecular weight between 10 kDa to 80 kDa. On the other hand, protein spots from leaves were moderately resolved at pH 4 to 10 at molecular weight within 10 kDa to 50 kDa.

Although malaria had ever been virtually eradicated from Indonesia but currently malaria is recognized as a serious re-emerging threat to public health. This disease is caused by malaria parasite which is transmitted to human host by Anopheles mosquitoes as main vector. It has been widely observed that saliva of mosquito that transmits disease contains several factors that could enhance pathogen infection. Therefore, it should be possible to control pathogen transmission by vaccinating the host against the molecule(s) in saliva that potentiate the infection. However, immunogenic specific component in mosquitoes vectors of Malaria has not yet been identified so far. The objective of this study are to analyze protein profile of SDS-PAGE and to know the immunogity the protein extract of salivary gland from potential vector of Malaria i.e. An. aconitus We used immunogenic reaction between salivary gland extract of these vectors against pool of human sera which were collected from endemic area. The reaction conducted by the dot-blot analyze. SDS-PAGE studies showed 15 major polypeptide bands of 284, 100, 84, 75, 66, 57, 53, 48, 45, 38, 33, 29, 15, 14, and 11 kDa. The dot-blot studies showed that the protein extract of salivary gland from An. aconitus are immunogenic.

Background: Egg yolk is a rich and accessible source of yolk immunoglobulin (Y immunoglobulin). Presently, polyclonal antibodies from mammalian sources are used for diagnosis. Antibody production from egg yolk gives a higher yield and turnover than that from lab animals, and invasive methods such as phlebotomy and causing stress to the animals are not required. Due to the issues regarding mammalian antibodies, we aimed to evaluate the human anti-IgG polyclonal antibody production conjugated with peroxidase in egg yolk.Methods: Population of laying hens reared in Agriculture/Isfahan University of Technology were used in 2017. After immunizing hen against pure human IgG, specific IgY (yolk immunoglobulin) was purified from the yolk by sedimentation with polyethylene glycol (PEG6000). To assess the molecular weight and activity of the product, SDS-PAGE and ELISA-test were used, respectively.Results: The complete molecular weight of IgY was 180 kDa and the molecular weight of its light and heavy chains were 27 and 67 kDa, respectively.Conclusion: Antihuman IgG IgY had a purity above 90%. The product of this study can be used to measure IgG class antibodies in order to diagnose different diseases.

ABSTRACT Glomerular proteinuria is characterized by the loss of high-molecular-weight proteins (HMWPs), while tubulointerstitial proteinuria is characterized by the loss of low-molecular-weight proteins (LMWPs). The objective was to assess the molecular weight of urinary proteins (MWUP) in dogs with naturally acquired CKD and determine the proportion of HMWPs and LMWPs according to CKD stage. Twenty-eight dogs with CKD were recruited and divided into 4 groups based on serum creatinine (Cr) levels (group1: Cr<1,4, n=8; group2: 1,4<Cr<2,0, n=6; group3: 2,1<Cr<5, n=9; group4: Cr>5,0, n=5). The control group consisted of 5 healthy dogs. The MWUP was determined by SDS-PAGE. The urinary protein-to-creatinine ratio (UP/C) was used to quantitatively assess proteinuria. The electrophoresis pattern revealed a proportionally greater loss of HMWPthan of LMWP in all groups with CKD and an increased loss of LMWP in group 4 (P<0.05). These results suggest a predominance of glomerular injuries throughout all stages of CKD in these dogs and an increase in tubulointerstitial injury towards the end-stage of the disease. The results of the present study support the recommendation of SDS-PAGE as an effective technique for the qualitative assessment of proteinuria, as well as a method for assessing the severity and location of renal injury.
